The Anatomy of I/O Bottlenecks

I/O bottlenecks can emanate from various sources, each contributing to the hindrance of data transfer efficiency. One factor is the exponential growth in data volume and complexity, placing an increased demand on storage infrastructure. As systems grapple with the sheer magnitude of data, read and write operations may experience delays, resulting in sluggish performance.

A primary contributor to I/O bottlenecks is what we commonly refer to as split I/Os. These refer to additional I/O operations necessitated by the file system breaking up a file into multiple fragments, resulting in excessive traffic to and from storage. In the pursuit of a dynamic file system accommodating varied file sizes, scalability, and accessibility through different I/O sizes, files are inherently divided into multiple pieces. With the escalation in volume sizes and the proliferation of files on a volume, split I/Os become a more pronounced issue.

While not all file fragments threaten I/O performance, the reality is that, more often than not, I/O operations are not aligned with file allocations. Consequently, a single I/O tasked with processing data for an application may be split into multiple I/Os by the file system. This issue intensifies when free space becomes severely fragmented, accelerating the rate of overall fragmentation and the corresponding occurrence of Split I/Os. Recognizing that Split I/Os are detrimental to storage performance, the prevention and elimination of such occurrences emerge as pivotal measures, offering one of the most straightforward ways to significantly enhance storage performance.

The Impact of I/O Bottlenecks

The repercussions of I/O bottlenecks extend beyond mere inconvenience, significantly affecting the overall performance and responsiveness of a system. Slower data access times translate to delays in executing critical tasks, hampering productivity and user satisfaction. In scenarios where real-time data processing is essential, such as in financial transactions or database queries, the impact of I/O bottlenecks can be particularly severe.

Moreover, the wear and tear on hardware components due to excessive I/O operations can lead to a shortened lifespan of storage devices, posing long-term implications for organizations, requiring frequent hardware replacements, and contributing to increased operational costs.

What is I/O Performance?

I/O performance measures the speed at which data is transferred between a Windows Server’s hardware components and its storage devices. This crucial aspect significantly impacts system responsiveness, application loading times, and overall server efficiency. Even with advancements in CPU power, disk drives (HDDs or SSDs), storage controllers, system memory (RAM), and network interfaces, the challenge of I/O bottlenecks persists.

Impact of Poor I/O Performance on Windows Servers

1. Slow Application Performance: Picture a scenario where a critical sales dashboard takes agonizing seconds to load, leaving frustrated users staring at a spinning wheel rather than timely insights. Poor I/O performance translates to sluggish application response times, eroding productivity and sapping user satisfaction.
2. Increased Downtime: Imagine a high-traffic period—a rush of data flowing in and out—only for the server to buckle under the pressure, crashing unexpectedly. Inadequate I/O performance can transform a bustling operational environment into a realm of downtime, disrupting operations and risking business continuity.
3. Reduced Virtualization Efficiency: Envision a virtualized landscape where the efficiency of virtual machines (VMs) hinges on seamless I/O operations. A server with lackluster I/O performance stifles the potential of VMs, constraining scalability and hindering resource optimization.
4. Backup and Recovery Challenges: Consider a critical moment when disaster strikes, and recovery efforts are underway. Sluggish I/O performance stretches the time needed to back up data or restore it from backups, delaying recovery and undermining business resilience.
5. Longer Boot and Shutdown Times: Put yourself in the shoes of a user awaiting system access. Slow I/O operations during startup and shutdown extend wait times, leaving users tapping their fingers and affecting the overall accessibility of the system.

*As much as virtualization has helped server efficiency, the downside is it adds complexity to the data path, otherwise known as the “I/O blender effect”, that mixes and randomizes IO streams. When there are multiple VMs on a host, or multiple hosts with VMs that use the same back-end storage system (e.g., a SAN) a “blender” effect occurs when all these VMs are sending I/O requests up and down the stack. This can create huge performance bottlenecks. In fact, perhaps the most significant issue that virtualized environments face is the fact that there are MANY performance chokepoints in the ecosystem, especially the storage subsystem. These chokepoints are robbing 30-50% of your throughput.

The Data Center View

Using some simple “whiteboard” graphics, let’s start with the Data Center view. In every Data Center, you have the same basic hardware layers. You have your compute layer, your network layer, and your storage layer. The point of having this hardware infrastructure is not just to house your data, but it’s to create a magical performance threshold to run your applications smoothly so your business can run smoothly.

As long as your hardware doesn’t crash, and you don’t lose any data, and as long as all your applications fit nicely and neatly inside your performance boundary, well then, life is good!

The Troublesome Applications

But, in every organization, there are always, and we mean always, one or two applications that are the most harrowing in the business, that are pushing the performance boundaries and thresholds that your architecture can deliver, that simply need more performance.

We often see this as applications running on SQL or Oracle, it could be Exchange or SharePoint. We see a lot of file servers, web servers, image applications, and backups. It could be one of the acronyms: VDI, BI, CRM, ERP, you name it.

As soon as you have an application that is testing the I/O ceilings in your environment under peak load, what happens?

• applications get sluggish
• users start complaining
• back-office batch jobs start taking far too long
• backups start failing to complete in their window
• users running certain reports get frustrated

Now you’re getting all this pressure from outside of IT to jump in and solve this problem, and NOW.

Throwing Hardware ($$$) at the Problem

Typically, what do most IT professionals at least think that they must do to boost application performance? They think they must throw more hardware at the problem to fix it. This means adding in more servers and more storage, expensive storage. Probably an All-flash array to support a particular application, or maybe a Hybrid to support another application. And ultimately this ends up being a very, very expensive, not to mention disruptive, way to solve performance problems.

Spending Less (Much less) To Solve Application Performance Problems

What if you could install some software that would magically eliminate the toughest performance problems on your existing hardware infrastructure?

We have thousands of organizations using this software-only solution, some of them the largest organizations in the world, and most of the time they’re seeing at least a 50% performance boost in application performance, but many of them see far more than that.

Our website is littered with case studies citing at least a doubling in performance. It’s the reason why Gartner named us the Cool Vendor of the year when we brought this technology to the market.

Now you may wonder, “how can a 100% software approach have this kind of impact on performance?” To understand that, we have to get under the hood of this technology stack to see the severe I/O inefficiencies that are robbing you of the performance that you paid for.

The Severe Performance-Robbing I/O Inefficiencies

As great as virtualization has been for server efficiency, the one downside is how it adds complexity to the data path. Voila, the I/O blender effect that mixes and randomizes the I/O streams from all of the disparate VMs that are sitting on the same host hypervisor. And, if that performance penalty wasn’t bad enough, up higher you have a performance penalty even worse with Windows on a VM. Windows doesn’t play well in a virtual environment, doesn’t play well in any environment where it’s abstracted from the physical layer. So, what this means is you end up with I/O characteristics that are far smaller, more fractured, and more random than they need to be. Physical systems experience similar inefficiencies also. It’s the perfect trifecta for bad storage performance.

For peak application performance, you want:

• an I/O profile where you’re getting nice, clean contiguous writes and reads
• a nice healthy relationship between I/O and data
• maximum payload with every I/O operation
• sequential manner of your traffic

In a virtual environment running a Windows machine, this is not what you get. Instead, what you get is many small, tiny reads and writes. And all of this means that you need far more I/O than is needed to process any given workload, and it creates a death-by-a-thousand-cuts scenario. It’s like pouring molasses on your systems. Your hardware infrastructure is processing workloads about 50% slower than they should. In fact, for some of our customers, it’s far worse than that. For some of our customers, their applications barely run. And, for some, their users can barely use the application because they’re timing out so quickly from the I/O demand.

2 Patented Technologies to Restore Performance

Our patented DymaxIO software solves this problem, and we solve it in two ways.

The first way that we solve this problem is within the Windows file system. We add a layer of intelligence into the Windows OS where it’s just a very thin file system driver with near zero overhead. It would be difficult for you to even see the CPU footprint! DymaxIO is eliminating all the really small, tiny writes and reads that are chewing up your performance, and displacing it with nice, clean, contiguous writes and reads. So now you’re getting back to having a very healthy relationship between your I/O and data. Now you’re getting that maximum payload with every I/O operation. And the sequential nature of your traffic down to storage has dramatically improved reducing unnecessary I/O where that matters the most.

So, this engine all by itself has a huge application performance impact for our customers, but it’s not the only thing that we do.

The second thing DymaxIO does to help improve overall performance is establish a Tier-0 caching strategy using our DRAM caching engine. DymaxIO is using the idle available DRAM already committed to these VMs that is sitting there and not being used, and we’re putting that to good use. Now, the real genius behind this engine is it’s completely automatic. Nothing has to be allocated for cache. DymaxIO is aware moment by moment of how much memory is unused and only uses that portion to serve reads. You never get any kind of memory contention or resource starvation. If you have a system that’s under-provisioned and memory constrained, that engine will back off completely.

Seeing is Believing

When you consider these 2 engines: one optimizing Writes, and another optimizing Reads, you may wonder “what does this all mean”? Honestly, the best way is to simply just install the software. Try it for yourself on a virtual server or physical server and see your application performance boost. Let it run for a few days, and then pull up our built-in time-saved dashboard where you can see the amount of I/O that we’re offloading from your underlying storage device. And more importantly, see how much time that’s actually saving that individual system. Now, you might want to do a before and after stopwatch test or you might want to look at your storage UI to get a baseline of workloads before so you can see what happens, but really, all you have to do is just install the software and experience the performance and then pull up that time saved dashboard communicating the benefit that means the most to your business: time saved.

Typical Results

Now as far as typical results, this screenshot represents a median of the typical results you can expect. You see the number of I/Os that DymaxIO is removing, but take a look at the percentages right there in the top middle. You’re seeing 45% of Reads that are being served out of DRAM, meaning it’s being offloaded from going down the storage. On the right side, you’re seeing 41% of Write I/O that’s being eliminated. Now, in this typical median system, that saves over 6 days of I/O time over 90 days of testing. This I/O time saved is going to be relative to the intensity of the workload. There are some systems with our software that are saving 5.5 hours in a single day. This translates to a massive application performance boost! ASL Marketing had a SQL import batch job that was taking 27 hours. We cut it down to 12 hours! Talk about huge single-day time savings! ASL case study

What is the sweet spot where you can get optimum performance? Well, we have found out that if a customer can maintain at least 4GB of available DRAM that our software can leverage for cache, it means give or take, but on average, you’re going to see 40% or more of Reads being served. What does that mean? It means essentially this: you have just eliminated over 40% of your Read traffic that’s gone down to your storage device, you’ve opened up all of your precious throughput from the very expensive architecture that you paid for, and you’re serving a large part of your traffic from the storage media that’s faster, more expensive than anything else, 15 times faster than an SSD sitting closer to a processor than anything else.

If you can crank up the 4GB to something even larger, you’re going to get a higher cache hit rate. A good example is the University of Illinois. Their hardest-hitting application was sitting on an Oracle database, it was supported by a very expensive All-flash array. It still wasn’t getting enough performance and so many users were accessing that system. They installed our software and saw 10X performance gains. And that’s because they were able to leverage a good amount of that DRAM and we were able to eliminate all these small, tiny reads and writes that were chewing up their performance (University of Illinois case study).

The typical results screenshot from the DymaxIO dashboard also showed 40%+ Write I/Os Eliminated. This is due to our IntelliWrite technology which dramatically reduces file fragmentation as data is written to storage. This also contributes to large performance gain while Writes are being done and that is especially significant in overcoming the I/O Blender effect. This reduction in Write I/Os also makes a significant contribution to preventing future Read I/Os since the file system will not have to do as many Split I/O operations. Split I/Os cause a single request to access a piece of data to be broken into multiple I/Os requests by the file system due to file fragmentation.

If you have a physical server, physical servers are typically over-provisioned from a memory standpoint. You have more available memory to work with, and you’ll see huge gains on a physical server.

Automatic and Transparent

All this optimization is happening automatically. It is all running transparently in the background. DymaxIO is set and forget running at near zero overhead. You may wonder, what are some typical use cases or customer examples? You can read our case studies with examples of customers where we saved them millions of dollars in new hardware upgrades, helped them extend the life and longevity of their existing hardware infrastructure, doubled performance, tripled SQL queries, cut backup times in half, you name it.

You can easily install and evaluate DymaxIO on your own on one virtual server and one physical server. However, in a virtual environment, you will see far better performance gains if you evaluate the software on all the VMs that are sitting on the same host hypervisor. This has to do with the I/O blender effect and chatty neighbor issues. So, if that’s the case, and you have more than 10 VMs on the host, you may want to contact us about getting our centralized management console that makes deployment to many servers at once easy. It’s that simple.

We look forward to helping you solve the toughest application performance problems in your Windows environment while saving you a ton of money!

Community Medical Center (CMC) had one initial requirement – find a FAL remediation solution for their MEDITECH electronic health record (EHR) application to maintain 24/7 availability and avoid downtime. What surprised them the most was the extent of the performance boost from using DymaxIO I/O transformation software.

“Our doctors and clinicians were losing too much time on basic tasks like waiting on medical images to load, or scanning images, or even just navigating from screen to screen within the application. The easy answer is to buy new server and storage hardware; however, that’s also a very expensive answer. When you’re a small hospital, you need to squeeze every last drop of performance out of your existing infrastructure. Since we don’t have the budget luxury of doing hardware refreshes every three years, we need to get at least five years or more from our storage backend,” said IT Director at Community Medical Center.

The Performance Benefits

The IT Director continued, “We initially purchased DymaxIO I/O transformation software to meet an availability requirement, but what surprised us the most was how much value it to added to our aging storage infrastructure by offloading a significant amount of I/O traffic. Not only did we get an immediate performance boost for MEDITECH, but we soon realized that we needed to try DymaxIO on our other Tier-1 applications like NextGen, MS-SQL, MS Exchange, Citrix XenApp, and others.”

The IT Director identified 35 key virtual servers that ran an assortment of different applications, like NextGen EHR (supported by a MS-SQL database), MS Exchange, Citrix XenApp, GE Centricity Perinatal, and others. In aggregate, DymaxIO offloaded 43% of all read traffic from storage and 29% of write traffic. With well over half a billion I/Os eliminated from going to storage, the median latency savings meant an aggregate of 157 days of cumulative storage I/O time saved across all the servers over a three-month period. When examining the last 24 hours from CMC’s single heaviest workload on a MS-SQL server, DymaxIO offloaded 48,272,115 I/O operations from storage (48% of read traffic / 47% of write traffic) – a savings of seven hours in storage I/O time

“There’s no way we would have achieved a 5-year lifecycle on our storage system without DymaxIO offloading so much I/O traffic from that subsystem. We had no idea how many I/O operations from virtual server to storage were essentially wasted activity due to Windows write inefficiencies chewing up IOPS or hot data that is more effectively served from available DRAM,” said the IT Director.

The Full Story

The post MEDITECH Hospital Speeds EHR & MS-SQL with DymaxIO I/O Transformation Software appeared first on Condusiv - The Diskeeper Company.

The one common denominator is that all these applications ran on Windows servers – Windows Server 2012R2 / 2016 / 2019.

“As we learned through this exercise with Condusiv’s DymaxIO I/O transformation software, we were getting hit really hard by thousands of excessively small, tiny writes and reads that dampened performance significantly,” said Greg Landes, Manager of Systems Services. “Everything was just slower due to Windows Server write inefficiencies that break writes down to be much smaller than they need to be, and forces the all-flash SAN to process far more I/O operations than necessary for any given workload.”

Landes continued, “When you have a dump truck but are only filling it a shovelful at a time before sending it on, you’re not getting near the payload you should get with each trip. That’s the exact effect we were getting with a surplus of unnecessarily small, fractured writes and subsequent reads, and it was really hurting our storage performance, even though we had a really fast ‘dump truck.’”

“We had no idea how much this was hurting us until we tried DymaxIO to address the root-cause problem to get more payload with every write. When you no longer have to process three small, fractured writes for something that only needs one write and a single I/O operation, everything is just faster,” said Landes.

When testing the before-and-after effect on their production system, Greg and his team first measured without DymaxIO. It took 4 hours and 3 minutes to process 1.57TB of data, requiring 13,910,568 I/O operations from storage. After DymaxIO, the same system processed 2.1TB of data in 1 hour and 6 minutes, while only needing to process 2,702,479 I/O operations from underlying storage. “We processed half a terabyte more in a quarter of the time,” said Landes.

“Not only did DymaxIO dramatically help our write-heavy MS-SQL and Oracle Servers by increasing performance 50–100% on several workloads, we saw even bigger gains on our read heavy applications that could take advantage of DymaxIO’s patented DRAM caching engine, that put our idle, unused memory to good use. Since we had provisioned adequate memory for these I/O-intensive systems, we were well positioned to get the most from DymaxIO.”

“We thought we were getting the most performance possible from our systems, but it wasn’t until we used DymaxIO that we realized how inefficient these systems really are if you’re not addressing the root cause performance issues related to the I/O profile from Windows servers. By solving the issue of small, fractured, random I/O, we’ve been able to increase the efficiency of our infrastructure and, ultimately, our people,” said Landes.

Let’s Look at How

As much as virtualization has helped server efficiency, the downside is it adds complexity to the data path, otherwise known as the I/O blender effect, that mixes and randomizes I/O streams.

If that performance penalty wasn’t bad enough, Windows doesn’t play well in a virtual environment, or any environment where it’s abstracted from the physical layer. So you end up with a surplus of excessively small, tiny writes and reads.

That means your application performance hasn’t been penalized once, but twice, with I/O characteristics that are much smaller, more fractured, and more random than they need to be.

This death by a thousand cuts scenario means systems process workloads about 50% slower than they should on the typical Windows Server because far more I/O is needed to process any given workload.

Most IT professionals think the only way to solve performance problems is to throw expensive hardware at the problem, new servers or new storage – but this does not eliminate the I/O blender effect.

To ensure that you never have to upgrade your storage backend for performance reasons, all someone has to do, in fact, is simply try DymaxIO fast data performance software on any Windows server, virtual or physical, and watch your toughest performance challenges disappear – we guarantee it!

DymaxIO fast data performance software eliminates small tiny writes by displacing them with large, clean, and contiguous writes so every I/O operation delivers more payload.

In addition, DymaxIO fast data performance software further reduces I/O to storage by establishing a tier 0 caching strategy by automatically serving hot reads from memory that is idle and otherwise unused. This means the typical DymaxIO customer experiences at least 50% faster application performance, while many see twice as much or more depending upon the amount of available DRAM.

Whatever bottleneck or I/O ceiling that is causing slowness, Condusiv’s DymaxIO fast data performance software guarantees to solve it so your applications run smoothly, like Condusiv did for thousands of companies like these:

Backups and snapshots can still be used to retrieve those files but that can be akin to finding a needle in a haystack and laborious to recover. Which backup contains the most recent version? Was the file created or modified before the last backup or snapshot took place? In that case, the backup or snapshot isn’t of any help.

First Line of Defense

Condusiv customers use Undelete^® as a first line of defense for data protection on file servers to keep administrators from digging through backups and snapshots for individual files or folders. If any user accidentally deletes a file over a network share, it goes into Undelete’s recovery bin. This ensures real-time protection of all files on a file server that can be quickly and immediately recovered. Many organizations use Undelete for their HelpDesk team to recover individual files instead of tasking IT staff with the tedious task of accessing backups for a single file.

Moreover, Undelete keeps prior versions of documents, so if your CEO accidentally overwrites his PowerPoint presentation, you can always recover prior versions of saved files that share the same file name.

One of the features admins like most about Undelete is the ability to see who deleted a file, when it was deleted, and who created the file. This is especially useful if you are concerned with the possible nefarious activities of staff.

From Our Undelete Customers

Undelete customers participated in an Undelete product survey and told us what they like the most, and here are some of their answers:

• Ease of restoring files deleted from network locations without having to use backups.
• We have backups on daily basis, but nothing that keeps the deleted network files available and reported on who deleted. Undelete covers this issue.
• We needed a product that provided “Recycle Bin” functionality for network shares. Undelete Server goes one step further and even tracks revisions. Great product.
• Sometimes, human errors occur and files get overwritten or deleted, which means losing several hours of work since the last regular backup. We need to be able to instantly recover deleted files – this is not possible with scheduled backups or VSS.
• Versioning control on modified or overwritten files
• Much quicker and simpler than reverting to any BACKUP/RESTORE software. Plus, our HelpDesk can use it.
• On a number of occasions, users will “lose” or delete files. It is simpler to use Undelete than scour through backups.
• Close the time gap between an incident and the last regular backup
• HelpDesk needed this tool to offload menial requests from IT staff to dig through backups for one file

Part 1: An Overview of The Features and Components in Undelete Server

• Recovery Bin

• Search Feature

• Version Protection for Microsoft Office files and other file types

• Emergency Undelete

• SecureDelete

• Wipe Free Space

• Undelete Desktop Client Component

Recovery Bin

The Recovery Bin feature is similar to the Windows Recycle Bin. Deleted files aren’t really deleted—they’re simply moved to the bin and held there until the bin is “emptied” or purged.

This allows you to recover files easily after they have been deleted — so recovering these “deleted” files is only a few mouse clicks away.

However, the Recovery Bin differs from the standard Windows Recycle Bin in several important ways:

• It allows you to recover files deleted by any method, including Windows Explorer and other applications—even files deleted from the Windows command prompt!
• You can have a Recovery Bin for any individual disk volumes on your computer, or use a single, “common” Recovery Bin for all your disk volumes–even on Cloud Storage services such as Microsoft OneDrive.
• When files are “deleted” and moved by Undelete into the Recovery Bin, they are displayed in a manner very similar to Windows Explorer. You (or your users) can see and recover the deleted files and the folders as easily as browsing for “normal” files.
• The Undelete Server and the Desktop Client component of Undelete allow you to see the contents of the Recovery Bins on remote computers running Undelete Server Edition, allowing you or your users to recover “deleted” files across your network (typically from network file servers). This feature alone is a “life saver” for many System Administrators and Help Desk technicians. It’s no longer necessary to search backup when a network user accidentally deletes a file from the file server.

There are actually two different ways you can recover deleted files from remote Recovery Bins: Mapped share access and node-to-node access.

Computers running Undelete Server or Client can access deleted files from mapped network shares (if the computers where the shares reside are running Undelete Server Edition). Computers running Undelete Server have the added capability of being able to access the full Recovery Bin on remote computers running either Undelete Professional Edition or Undelete Server Edition.

Note: You must have adequate permissions and ownership of a file in order to recover it from the Recovery Bin.

To view the contents of the Recovery Bin, double-click the Recovery Bin icon on your desktop. The files shown in the Recovery Bin display are files that have been deleted by any of a variety of methods, including the Windows File Explorer, or any other application capable of deleting files. It also includes files deleted via the Windows command prompt. (Note, however, that long filenames may be shortened to the DOS 8.3 file naming convention when files are deleted from the command prompt.)

You can have more than one Recovery Bin on your computer. Recovery Bin Properties (Settings menu > Properties ribbon icon > Global Settings tab) let you can specify individual Recovery Bins for each disk volume.

Or you can use one common Recovery Bin for all drive volumes—and even have the common Recovery Bin files sync to the Cloud through a Cloud Storage service such as Microsoft OneDrive. Undelete supports a common Recovery Bin on OneDrive by designating the Bin to be located on the OneDrive local Sync folder location. This is typically located on the C: drive under the C:\Users folder under the User’s profile folder, e.g., C:\Users\{user’s profile folder name}\OneDrive.

To set a single Common Recovery Bin for all drives, click the Settings menu > Properties ribbon icon > Global Settings tab > set “Use one Recovery Bin for all drives”. Designate the Recovery Bin location by selecting the drive and entering the full path under the Common Bin tab.

See below for more information on setting up a common Recovery Bin.

Search Feature

The Search Recovery Bin feature is designed to help you find the file you want to recover from the Recovery Bin, as the Recovery Bin may contain thousands of “deleted” files.

A Search feature for deleted files not saved in the Recovery Bin is also available.

See below for more details under Using the Search Feature.

Version Protection for Microsoft Office and Other Files

This powerful feature allows Users to recover previous versions of almost any file type, including the ability to restore an opened file before edits began.

Undelete captures commonly-used Microsoft Office files when they are overwritten during a save operation. By default, Undelete Server captures versions of Microsoft Word, Excel and PowerPoint files, but additional file types can be added as needed to allow you or your users to recover previous versions of just about any type of file.

Undelete also supports copy to the Recovery Bin on first write for an opened file that has a file type designated for versioning. Undelete captures the first write to the disk for these files. This provides the User the ability to restore the initial state of the file before edits began.

Other file types can easily be added via the Settings menu > Properties ribbon icon > Versions tab.

Emergency Undelete

Emergency Undelete is a separate utility included with Undelete Server used to recover accidentally deleted files before installing the full Undelete product. Since installing software on a computer can overwrite deleted files and make them unrecoverable, Emergency Undelete runs directly from a removable storage media (such as a CD-ROM or thumb-drive) without any installation.

Important!

Once a file is deleted, the chances of fully recovering that file decrease considerably when other activity occurs on the same disk volume. To improve the possibility of a complete recovery of a file that has been accidentally deleted, Condusiv Technologies recommends the following steps:

1. Stop all activity on the disk volume where the accidentally deleted file resided. Do not save any files that are currently open, since this causes a write operation on the disk.
2. If the computer is on a network, disconnect the network cable if possible. This prevents disk activity caused by remote users from writing over the file you want to recover. (Keep the network cable connected if you want to recover the file to a disk volume on are mote computer.)
3. After Emergency Undelete has located the file, recover the file to a local or remote disk volume other than the volume from which the file was recovered. This prevents the deleted file from accidentally being written over by the write operation of the recovery process.

Note: On FAT volumes, files with short names (8.3 format) that have really been deleted will have the first character of the filename replaced by a tilde (~). For example, a file named test.txt, when deleted, will be renamed to ~est.txt and will be displayed that way in the Emergency Undelete windows.

See for more information about Emergency Undelete.

SecureDelete

There may be times when, due to corporate security policies or personal preference, you need or want files to be completely erased. The SecureDelete feature in Undelete provides this capability.

When enabled, SecureDelete not only deletes the file, but it overwrites the disk space the file previously occupied, thereby removing any remaining traces of the file left on the disk. This is done by overwriting it with a specific bit pattern specified for this purpose by the National Security Agency (NSA) for the Department of Defense (DOD).

Finally, after the file has been overwritten, it is deleted. The SecureDelete procedure makes it virtually impossible for anyone to access sensitive file data from a disk after it has been deleted from the Recovery Bin.

The SecureDelete option can be set to overwrite files as they are purged from the Recovery Bin, or immediately as they are deleted.

See for more information about the SecureDelete feature.

Wipe Free Space

Similar to the SecureDelete feature, the Wipe Free Space feature will overwrite any free space on the selected disk volume with a specific bit pattern, making it virtually impossible to read or recover any data that was previously written in the free space.

See for more information about the Wipe Free Space feature.

Undelete Desktop Client Component

The Undelete Desktop Client component, which is used with Undelete Server Edition, allows you (or more importantly, your users) to find and recover deleted files from remote Recovery Bins, such as those on a file server. The Undelete Desktop Client operates similarly to the Recovery Bin interface in Undelete Professional Edition, except it only “sees” Recovery Bins on remote systems. It does not have a “local” Recovery Bin where deleted files are stored. Users are only shown and allowed to recover files on shared network drives for which they have sufficient ownership or system privileges. NTFS permissions are applied and users will not be able to restore data from file shares they do not have permission to.

The Undelete Desktop Client saves time and trouble for System Administrators and Help Desk personnel by enabling users to recover their own deleted files from remote file servers. Undelete Server includes unlimited Desktop Client licenses.

Using the Undelete Server Recovery Bin to Recover Files

The Undelete Recovery Bin interface contains four menus: File, Home (the default menu), Tools, and Settings.

The Home, Tools, and Settings menus each contain a Ribbon Icon bar. Hovering over a Ribbon bar icon or button will show a brief description of what the icon / button does.

The User may elect to add any of the Ribbon icons into the Quick Access menu (located in upper-left of the Undelete Window Title bar) by right-clicking on the icon and choosing “Add to Quick Access Toolbar”.

Below the Ribbon Icon bar is the Recovery Bin, which gives a folder view of the location of captured deleted files.

The Recoverable Files section to the right of the Recovery Bin shows the files that can be recovered. The default view is to show Deleted Files and File Versions. The User can choose to toggle the Deleted Files and File Versions buttons in the Show section of the Ribbon bar in the Home menu.

Recovering Files

Recovering a file or file version to its original location is a simple process:

In the Recovery Bin folder section, highlight the folder of interest that has files to be recovered.

Highlight one or more files in the Recoverable Files list, and click the Recover ribbon icon in the Home menu, or right-click the highlighted file(s) and choose Recover:

The default Recovery location is shown in the Recover to field. Click OK recovery the file(s) to their original folder location:

To recovery the file(s) to a different location, double-click the double-dots directory icon, and navigate to the desired location, and then click OK to recover the file(s):

Alternatively, if you have Windows File Explorer open you can simply drag and drop the selected files into a File Explorer folder (Including the User’s Desktop).

Opening Files Prior to Recovering Them

The User may choose to open files to inspect their contents prior to recovering them.

This can be done in several ways, depending on whether the file has any Copies in the Recovery Bin.

A highlighted file without Copies can be opened with its associated application by:

• Double-clicking the file

• or clicking the Open icon in the Actions section of the Ribbon bar

• or right-clicking the file and choosing Open

A highlighted file that has Copies can be opened from the View Copies dialog box.

The View Copies dialog box will open when the User either:

• Double-clicks a file with Copies

• or clicks the View Copies icon in the Actions section of the Ribbon bar

• or right-clicks the file and chooses View Copies

In the View Copies dialog box, the User can open each copy with its associated application by double-clicking it, or by right-clicking on the copy and choosing Open. Alternatively, the User may choose the program to open the file by right-clicking on the copy and choosing Open With, and then selecting Choose Program.

Undelete Server Recovery Bin Properties—Settings

Use the Settings menu > Properties ribbon icon to access the Recovery Bin Properties and Settings.

Within the Recovery Bin Properties dialog box, you can manage the settings for individual drive volume Recovery Bins or common Recovery Bins.

This includes:

• Global Settings that apply to all Recovery Bins – Individual Recovery Bins versus a Common Recovery Bin; SecureDelete all files immediately; enable/disable Recovery Bins; sizing rules for Recovery Bins; enable/disable the saving of deleted zero length files; enable/disable Recovery Bin Virus Protection; enable/disable the ability to turn on SecureDelete on purge for Recovery Bins; enable/disable the “Confirm each delete from the Recovery Bin” warning.

• Versions – Enable/disable saving of file versions; specify the number of versions saved per file; specify the file type extensions that will be saved in the Recovery Bin as versions.

• Common Bin – Specify the location of the Common Bin; specify its size; enable/disable feature to purge files older than a specified number of days.

• Individual drive volume Recovery Bin settings – Enable/disable Bins; set Recovery Bin size; enable/disable feature to purge files older than a specified number of days; enable/disable Automatic Wipe Free Space feature.

Global Settings Tab

• Each volume has its own Recovery Bin or Use one Recovery Bin for all volumes – Set whether each drive volume has its own Recovery Bin or whether a common Recovery Bin is used for all volumes.

• SecureDelete all files immediately – Enabling this and clicking OK will cause Undelete to run SecureDelete immediately on all files in all Recovery Bins. This action is not reversible. Once the cycle has completed, even the Search feature will not be able to recover files.

• Enable Recovery Bin on newly detected volumes – This is turned off by default.

• Turn off Recovery Bin on all volumes – There may be times when the User wants to temporarily turn off all Undelete Processing of deleted files. This is the setting to do that.

• Automatically Resize Recovery Bin based on free space – Turned on by default to best support the changing nature of free space on User systems.

• Make Recovery Bin a fixed size – Turned off by default. When enabled, it has two mutually exclusive options: Auto Purge when Bin becomes full, and Disable Recovery Bin when Max Size is reached. Additionally, when this is turned on the option to also Display Recovery Bin Full warnings is available.

• Do not save zero length files – Turned on by default. There are times when the Operating System and applications will create a files that do not have any contents in them—such as temporary files. Not saving these files to the Recovery Bin saves time and processing overhead.

• Enable Recovery Bin Virus Protection – Turned on by default.

• Enable Recovery Bin SecureDelete on purge – Turned off by default. Turn on this setting to allow the SecureDelete feature to be available for Individual drive volume Recovery Bins. Note that when this is enabled, all individual Recovery Bins will be set to SecureDelete files from their volumes from that point forward. The SecureDelete feature can be disabled as needed on individual Recovery Bins however.

• Enable Automatic Wipe Free Space – Turned off by default to reduce processing overhead. Useful on secure systems that have to maintain a high level of security for deleted files. The wiping of free space will prevent the Search feature from being able to locate deleted files that are not in the Recovery Bin.

Versions Tab

• Enable saving of file versions in the Recovery Bin – Turned on by default. Allows the saving of designated file types as changes are made to an opened file during Saves.

• Limit each file to – Set to 5 by default.

• Save versions of these selected file types – By default, Microsoft Office file types for Microsoft Word, Excel, and PowerPoint are included, and additional file types can be added as desired.

Common Bin Tab

• Specify the Volume and Full Path where you want the Recovery Bin to be located – When the Use one Recovery Bin for all volumes setting in the Global Settings tab is enabled, the Volume pull down menu and Path fields become available to be set. The Path field needs to have the Full Path to the Common Bin specified.

• Recovery Bin will automatically resize to [X] percent of free space – Defaults to 20 percent, and can be adjusted up to 80 percent using the scroll controls or by changing the horizontal slider control.

• Purge files older than X days – Turned off by default but can be set to the desired number of days. When enabled, defaults to 7 days.

Individual Drive Volume Tabs

• Enable a Recovery Bin on this volume – This setting may be enabled by default if the User did not change the setting during the Undelete product installation. When enabled, saves files deleted from the selected drive so that they can be recovered at some point in the future. This applies to the individual Recovery Bin associated with this drive. This Recovery Bin may also be functioning as the Common Recovery Bin if this drive has been selected as the location for the Common Recovery Bin.

• Recovery Bin will automatically resize to [X] percent of free space – Defaults to 20 percent, and can be adjusted up to 80 percent using the scroll controls or by changing the horizontal slider control. This setting is only applicable when Automatically Resize Recovery Bin based on free space is selected in Global Settings. As the amount of available free space changes on the volume, so will the space used by the Recovery Bin. Undelete will automatically purge older files from the Recovery Bin as necessary.

• SecureDelete files on this volume – When the Enable Recovery Bin SecureDelete on purge setting is enabled in Global Settings this option becomes available to set. When active, it is turned on by default. It will cause the permanent erasure of any file deleted on the selected drive. The deleted file will not appear in the Recovery Bin or the free space of the disk—rendering it completely unrecoverable. Use this feature only when absolutely required, as it does involve a performance hit.

• Purge files older than X days – Turned off by default. When enabled, defaults to 7 days. Use this option to control when files will be purged from the Recovery Bin. If a file in the Recovery Bin is more than the specified number of days old, it will be purged. This setting applies to both Auto-Size and Fixed-Size Recovery Bins.

• Save files deleted from Macintosh shares – Turned on by default. This option causes files deleted from SFM shares to be saved in the Recovery Bin (as long as the file is not on the Exclusion list). When this option is not enabled, files from Windows Services for Macintosh (SFM) shares are not saved in the Recovery Bin. We recommend leaving it enabled unless deletion performance on SFM shares is critical to your operation.

Using SFM, it is possible to make one or more shared folders or disks visible to Macintosh computers on your network. Special actions are required by Undelete to save files deleted from these shares. The actions needed to copy these files into the Undelete Recovery Bin involve more work and time than a normal file deletion, and thus Macintosh file deletions from SFM served shares may take more time. There is no impact to local files deleted from the Macintosh or to files on non-SFM shares on the server.

• Enable Automatic Wipe Free Space – Turned off by default. Useful on secure systems that have to maintain a high level of security for deleted files. Enable this option to keep the free space clean by wiping on a periodic basis going forward.

Auto-Wipe Free Space will overwrite free space on the selected volume with a specific bit pattern, making it virtually impossible to recover any data that may reside in the free space. It leaves the Recovery Bin intact and functioning, and wipes the free space clean.

The wiping of free space will prevent the Search feature from being able to locate deleted files that are not in the Recovery Bin.

Undelete Server Common Recovery Bin

The Common Recovery Bin is a single Recovery Bin, which is used to save deleted files from all applicable drive volumes, rather than having a separate Recovery Bin for each drive volume.

The common Recovery Bin has Cloud support. It can be setup as a subfolder within a local sync folder of a Cloud Storage service such as Microsoft OneDrive.

Enable a Common Recovery Bin

• Click the Properties ribbon icon in the Settings menu.

• In the Global Settings tab, change the selection to “Use one Recovery Bin for all volumes”. Click the Apply button.

• In the Common Bin tab:

• • Select the Volume where the common Recovery Bin will be located.

• • Enter the Full Path to the desired common Recovery Bin folder. For example, \UDBin.

• • Set the “Recovery Bin will automatically resize to” size as a percentage of the volume’s free space. This can be done by adjusting or entering a number less than or equal to 80 percent in the box provided, or by sliding the control to the desired percentage. The default Common Bin size is 20% of the volume’s free space.

• • Optionally check the “Purge files older than” check box to set the number of days.

• • Click OK:

Common Recovery Bin—Cloud Support

Undelete supports setting up a common Recovery Bin as a subfolder within the local sync folder of Cloud Storage services such as OneDrive.

The steps below outline how to setup a common Recovery Bin specifically for OneDrive, but similar steps can be taken to setup the common Bin for other Cloud Storage services that use a local sync folder.

Prior to managing the common Recovery Bin settings in Undelete, OneDrive must be setup with a new folder set to Sync with the Cloud.

As an example, this folder could be called UDBin and might be located in the User’s OneDrive Sync folder (e.g., C:\Users\{User_profile_name}\OneDrive\UDBin, where the specific User profile name would be shown).

Once OneDrive is setup with a folder set to Sync with the Cloud, the Properties for a common Recovery Bin can be set as above:

• Click the Properties ribbon icon in the Settings menu.

• In the Global Settings tab, select “Use one Recovery Bin for all volumes”. Click the Apply button.

• In the Common Bin tab:

• • Select the Volume where the OneDrive Sync folder is located.

• • Enter the Full Path to the OneDrive Sync folder. From the example above, this would be \Users\{User_profile_name}\OneDrive\UDBin.

• • Set the “Recovery Bin will automatically resize to” size as a percentage of the volume’s free space. This can be done by adjusting or entering a number less than or equal to 80 percent in the box provided, or by sliding the control to the desired percentage. The default Common Bin size is 20% of the volume’s free space.

• • Optionally check the “Purge files older than” check box to set the number of days.

• • Click OK.

Important Notes:

• Undelete Server: Using a Common Recovery Bin on a network server will cause the deleted files on the server to be copied into a single location. If a large number of deletions take place on the network, this can add considerable I/O overhead. This overhead is apparent not only on the disk where the Common Recovery Bin is located, but also on the disk from where the files are being copied. For this reason, a Common Recovery Bin is not recommended on a busy server. Instead, enable the Recovery Bin individually on each drive.

• When you specify a single, Common Recovery Bin for all your volumes, files that had been previously been moved to the local Recovery Bins (the folders named \RecoveryBin\) will not be automatically moved to the Common Recovery Bin.

• Creating a Recovery Bin in the OneDrive Sync folder will use local storage space just like any OneDrive folder that is Sync’d with the Cloud does. The User needs to keep this is mind when setting up the Common Bin size Properties.

• If the User moves their local OneDrive Sync folder location, they will need to manually update the Path location in the Common Bin tab.

Using the Undelete Server Search Feature

Access the Search feature from the Tools menu to recover files that have really been deleted and that are not located in the Recovery Bin.

This feature will search the Free Space on your system for the requested file(s).

Follow these steps to recover a file with the Search feature:

• Click on the Search ribbon icon under the Tools menu:

Specify the Name and Location of the file(s) for which you want to search. You can use wildcard characters (* and ?) in the Name field if desired:

Press the Browse button to navigate to the location you wish to start the search from. Choose one of the location options on the left such as My Computer. Then either click the volume you want to start the search in, or double-click the volume to navigate to the desired sub-folder, then click OK:

Click the Search button to start the search for deleted files. A Stop button will become available at the right of the Undelete interface. Click Stop to stop searching for a file

• Available files matching your search criteria will appear in the Recoverable Files section. Highlight the name of the file (or files) you want to restore.

• Click the Undelete Files button. The default location that the file(s) will be recovered to is a folder called “Recovered_Files” on the User’s Desktop. Click Browse to select a different location:

The default Recovery method will put the file(s) in the indicated folder.

The User may choose to organize the file(s) using the names of the original folders, under the indicated folder.

• Click OK to restore the deleted files.

Important Notes:

• In order to avoid overwriting data in free space, it is recommended that you restore a recovered file to a location where there is little or no chance of overwriting the original information (such as on a different drive then where the file originally resided).
• The Dig Deeper feature cannot recover files that have been overwritten by other files. As a result, there may be cases where a file is not recoverable.

• In keeping with file security requirements, you must be a member of the Administrators group to undelete files directly from the disk.

Undelete also allows the User to search for files in the Recovery Bin itself.

Using Version Protection and Recovery

Have you (or your users) ever worked on an important document, presentation or spreadsheet, diligently saving your work as you go, only to discover that the changes you’ve made to the file are not workable, and you need to “rollback” to an earlier saved version?

Undelete automatically captures commonly-used or custom designated Microsoft Office files when they are overwritten during a save operation. Microsoft Word, Excel and PowerPoint files are supported by default.

In addition to Microsoft Office file types, Undelete allows the User to designate other file types to be saved to the Recovery Bin.

When you save a version protected file, the previous version is deleted as the new version is being written. Undelete captures these previous versions of the file and makes them available to you in the Recoverable Files section.

This powerful feature allows Users to recover previous versions of almost any file type, including the ability to restore an opened file before edits began.

Other file types can easily be added via the Settings menu > Properties ribbon icon > Versions tab.

View Copies

When a file is deleted from a Windows folder that matches a file already saved in the Recovery Bin for the same folder, Undelete will indicate in the Recoverable Files list that there are File Copies available for the file:

The User can view these file copies in advance using the View Copies feature to help determine which copy should be restored.

To see a list of the available file copies for a selected file in the Recoverable Files list:

• Double-click the file, or

• Click the View Copies ribbon icon located in the Home menu, or

• Right-click the selected file and choose View Copies.

A list of the available copies will then be shown along with the date and time that each copy was last modified, and overwritten:

An individual file copy can be viewed with its associated application by:

• Double-clicking the file copy, or by

• Right-clicking the file copy and choosing Open, or by choosing Open With > Choose Program, to select the application used to open the file copy.

A selected file copy can be recovered by:

• Right-clicking the file copy and choosing Recover, or by

• Clicking the check icon located right below the menus:

A selected file copy can be deleted if desired by:

• Right-clicking the file copy and choosing Delete, or by

• Clicking the X icon located right below the menus:

View File Versions in File Explorer

Undelete supports a right-click menu option for viewing File Versions in Windows File Explorer. If a selected file has File Versions saved in the Recovery Bin, the View Versions menu option will be available to right-click on:

This will open Undelete and display the available versions saved in the Recovery Bin.

An individual version can be viewed prior to recovery, or deletion, by opening it with its associated Windows application. This is done by:

• Double-clicking a selected file version, or by

• Right-clicking the file copy and choosing Open, or by choosing Open With > Choose Program, to select the application used to open the file copy.

A selected version can be recovered by:

• Right-clicking and choosing Recover, or by

• Clicking the check icon below the menus:

Similarly, a selected version can be deleted by:

• Right-clicking and choosing Delete, or by

• Clicking the X icon below the menus:

Using Emergency Undelete

Undelete Server include Emergency Undelete, a unique tool used to recover accidentally deleted files and directory folders before you’ve installed the full Undelete product. Note: Emergency Undelete is only included in the paid version of Undelete and is not included in the free trial.

Since the installation of any software can overwrite accidentally deleted files, Emergency Undelete runs directly off a removable storage media (such as a CD-ROM or thumb-drive), installing no files at all onto your disk drive. The operation of Emergency Undelete is similar to running the Search feature in either of Undelete. You should place the EmergUnd.exe file on removable storage media (such as a CD-ROM or thumb-drive) in the appropriate drive or attached to your computer before running the program.

Follow these steps to recover a file with Emergency Undelete:

• Locate the EmergUnd.exe file on your removable storage media (such as a CD-ROM or thumb-drive) and double-click it.

• Enter the name of the file you want to undelete in the Name: field of the Emergency Undelete display. You can use wildcard characters (such as *.doc or *.*) if you don’t recall the name of the file. Note that on FAT volumes, deleted files with short names (8.3 format) will have the first character of the filename replaced by a tilde (~). For example, a file named test.txt, when deleted, will be renamed to ~est.txt and will be displayed that way in the Emergency Undelete windows:

• Enter the letter of the drive you want to search in the Location: field of the Undelete display. You can optionally enter a directory folder name (such as D:\My Documents). Use the Browse button to see the drives and folders on your computer.

• Click Search. This starts the search for deleted files.

• Once the search is complete, highlight the name of the file (or files) you want to undelete.

• Click Undelete Files…. This causes a new dialog box to be displayed.

• Enter the drive letter and directory folder name of the location where you want the undeleted file to be written in the Path: field. You can use the Browse button to navigate to the desired location. If you have more than one disk volume, be sure to specify a volume other than the one where the file was originally located. This prevents the new, recovered file from overwriting portions of the old, deleted file.

• Click OK. The file(s) you have selected will be recovered if possible and written to the location you have specified.

Important Tips for using Emergency Undelete:

Once a file is deleted, the chances of fully recovering that file decrease considerably when other activity occurs on the same disk volume. To improve the possibility of a complete recovery of a file that has been accidentally deleted, Condusiv Technologies recommends the following steps:

1. Stop all activity on the disk volume where the accidentally deleted file resided. Do not save any files that are currently open, since this causes a write operation on the disk.

1. If the computer is on a network, disconnect the network cable if possible. This prevents disk activity caused by remote users from writing over the file you want to recover. (Keep the network cable connected if you want to recover the file to a disk volume on a remote computer.)

1. After Emergency Undelete has located the file, recover the file to a local or remote disk volume other than the volume from which the file was recovered. This prevents the deleted file from accidentally being written over by the write operation of the recovery process.

Note: On FAT volumes, files with short names (8.3 format) that have really been deleted will have the first character of the filename replaced by a tilde (~). For example, a file named test.txt, when deleted, will be renamed to ~est.txt and will be displayed that way in the Emergency Undelete windows.

Using SecureDelete

There may be times when, due to corporate security policies or personal preference, you need or want files to be completely erased. The SecureDelete feature in Undelete provides this capability. When enabled, SecureDelete not only deletes the file, but it overwrites the disk space the file previously occupied, thereby removing any remaining traces of the file left on the disk. This is done by overwriting it with a specific bit pattern specified for this purpose by the National Security Agency (NSA) for the Department of Defense (DOD). Finally, after the file has been overwritten, it is deleted. The SecureDelete procedure makes it virtually impossible for anyone to access sensitive file data from a disk after it has been deleted from the Recovery Bin.

The SecureDelete option can be set to securely overwrite files and purge them from all Recovery Bins, or just as they are deleted.

SecureDelete options are accessible by clicking the Settings menu, and selecting the Properties icon in the Ribbon bar.

The Global Settings tab contains SecureDelete options that affect all Recovery Bins on the system:

• Enable Recovery Bin SecureDelete on purge – Enables SecureDelete to securely overwrite files as they deleted from individual volumes. Turn on this setting to allow the SecureDelete feature to be available for Individual drive volume Recovery Bins. Note that when this is enabled, all individual Recovery Bins will be set to SecureDelete files from their volumes from that point forward. The SecureDelete feature can be disabled as needed on individual Recovery Bins however.

• SecureDelete all files immediately – Immediately SecureDelete all files in all Recovery Bins. This action is not reversible. Once the cycle has completed, even the Search feature will not be able to recover files.

When both the Enable Recovery Bin SecureDelete on purge setting and the Each volume has its own Recovery Bin setting are enabled in Global Settings, this option becomes available to set. When active, it is turned on by default. It will cause the permanent erasure of any file deleted on the selected drive volume. The deleted file will not appear in the Recovery Bin or in the free space of the disk—rendering it completely unrecoverable. Use this feature only when absolutely required, as it does involve a performance hit.

The User may turn the SecureDelete feature on or off for each Drive Volume as desired by setting the “SecureDelete files on this drive” check box under each Drive Volume tab.

Note: SecureDelete relies on Undelete having sufficient permissions to write to the disk volume on which the files reside. In cases where Undelete does not have write permission, the file will be simply deleted in the normal fashion. However, the Wipe Free Space feature does not have this limitation and can “clean” areas of the disk volume that SecureDelete might not.

Similarly, the ribbon icon under the Tools tab provides a similar security feature that can be applied to all the free space on a chosen disk volume. This feature can be also set to automatically wipe free space on a per drive basis by setting the “Enable Automatic Wipe Free Space” check box under each Drive Volume tab.

Note: Wiping free space can sometimes take a while, and progress will be shown in the graphic at the top of the Drive Settings page and on the graphic in the main drive listing.

Using Wipe Free Space

The Wipe Free Space feature can be used manually and automatically.

Automatic Wipe Free Space

Enable this option for each drive:

Settings menu > Properties ribbon icon > set the “Enable Automatic Wipe Free Space” check box in each Drive Volume tab as desired.

This keeps the free space clean by wiping on a periodic basis going forward. Auto-Wipe Free Space will overwrite free space on the selected volume with a specific bit pattern, making it virtually impossible to recover any data that may reside in the free space. It leaves the Recovery Bin intact and functioning and wipes the free space clean.

Manual Wipe Free Space Ribbon Icon

If you want to manually initiate a Wipe Free Space cycle for a given volume without having to wait for the next automatic cycle to start, click the Wipe Free Space ribbon icon under the Tools menu.

Select a volume from the drop down menu and Undelete will begin wiping the free space of the selected volume immediately. Wiping free space can sometimes take a while to complete; a spinner will be shown in the upper right of the screen to let you know it is still working.

To see the status of any current or past Wipe Free Space job, click the Wipe Free Space pull-down located right below the Wipe Free Space ribbon icon and select Show Wipe Free Space Status. This will show in-progress jobs as well as any completed jobs.

Using Undelete Server Exclusion and Inclusion Lists

The Recovery Bin Exclusion and Inclusion Lists give you very complete, yet flexible control over what files are included and excluded from Recovery Bin processing. You can specify disk volumes, folders, individual files, or a particular file type you want included or excluded. Or, you can create custom inclusion and exclusion rules to fit a wide range of needs.

Exclusion List

Use the Recovery Bin Exclusion List to create a list of directory folders, files, and file types that you do not want to be processed by the Undelete Recovery Bin. When a deleted file (or the folder where it is stored) is excluded from the Recovery Bin, it really is deleted from the disk—not moved to another location on the disk (as other files normally are) when Undelete is running.

One example of a file type you would likely exclude from Recovery Bin processing are temporary files that you really do want to delete. These are often files with a .tmp file extension, but many other extensions are also used, depending on the applications you are running. A number of common temporary file types are excluded from Recovery Bin processing by default.

Typically, when you install an application, a number of temporary files are created, and then eventually deleted by the installation program. Also, compilers and Web browsers often create a large number of temporary files. There may be little chance you will ever need to recover these temporary files, so by excluding them from being processed by the Recovery Bin, the program really will delete them, and they won’t take up Recovery Bin space unnecessarily.

How to create entries for the Exclusion List:

To set options for the Exclusion list, click the Exclusion List ribbon icon in the Settings menu.

The default Exclusion List contains a number of file extensions, folder locations and Windows folders locations already excluded from Undelete processing.

The Exclusion List options vary depending on the type of exclusion being created.

To Exclude Volumes, Folders or Files:

• Select Volumes, Folders and Files from the Type pull down menu.

• From the Look in pull down menu, select the starting location to exclude from (Desktop, My Computer, or My Documents).

• If choosing My Computer, you can navigate to specific drives or sub-folders by double-clicking My Computer and navigating until you have selected starting point to exclude from.

• You can check the “Also exclude subfolders of selected folder” check box if desired to also exclude all folders and files below the highlighted folder.

• Multiple folders can be selected at one time by holding the Shift or Control keys.

• Click the Add button to add the new exclusion to the Exclusion List.

• Click OK.

To Exclude a Specific File Extension:

• Select File Extension (File type) from the Type drop down menu.

• Select the specific Volume you want the file type exclusion to apply.

• Click one or more file extensions from the list (Shift and Control work as usual). If the extension you want to exclude is not in the list, click the “Enter new” entry at the top of the list, and enter the file extension with a starting period followed by the desired file extension (e.g., .123). Enter an optional Description of the file extension, and then click OK. Highlight the newly added file extension.

• Click the Add button to add the file extension to the Exclusion List.

• Click OK.

To Create a Custom Exclusion

This option allows the User to create more flexible exclusions than the above Volume, Folder, File, or File Extension exclusions can.

Custom allows the User to specify specific volume, folder, file names and file extensions, as well as the starting folder or subfolder, and whether it applies to everything below the folder or not.

For example: Exclude all files with a *.123 file extension but only within all subfolders beneath C:\MyFolder.

To create a custom exclusion:

• Select Custom from the Type pull down menu.

• Choose from the following options from the I want to exclude pull down menus:

Files

Folders

Volumes

With the file extension (click the List button or fill in the file extension directly)

With the file name

With the full name

From the Folder

From the subfolder

From all folders

From all folders below

From the subfolder and all folders below

Fill in the path to the folder or click the Browse button to select the folder location to exclude by choosing one of the location options on the left such as My Computer. For My Computer, click the volume you want to exclude, or double-click a volume to navigate down to the desired sub-folder, then click OK:

From the volume (select the volume from the pull down menu)

From all volumes

And finally click the bottom pull down menu to select the volume to exclude from.

• Click the Add button to add the custom exclusion to the Exclusion List.

• Click OK.

To Remove an Exclusion from the List

An existing exclusion can be removed from the list by highlighting the exclusion and then clicking the Remove button, and then clicking Apply or OK. 

Inclusion List

Use the Recovery Bin Inclusion List to create a list of volumes, folders, files, and file types that you specifically, and exclusively, want to be processed by the Undelete Recovery Bin.

This is a new feature for this version of Undelete designed to make it easier for Users who want to have the Recovery Bin operate only for specific volumes, folders, files, or file types.

The User will be asked to confirm any entries added into the Inclusion List due to the exclusive nature of the feature.

To access the Inclusion List, click the Inclusion List ribbon icon in the Settings menu.

To set options for the Inclusion List, click the Inclusion List ribbon icon in the Settings menu.

The default Inclusion List is empty.

The Inclusion List options vary depending on the type of inclusion being created.

To Include Volumes, Folders or Files:

• Select Volumes, Folders and Files from the Type pull down menu.

• From the Look in pull down menu, select the starting location to include from (Desktop, My Computer, or My Documents).

• If choosing My Computer, you can navigate to specific drives or sub-folders by double-clicking My Computer and navigating until you have selected starting point to include from.

• You can check the “Also include subfolders of selected folder” check box if desired to also Include all folders and files below the highlighted folder.

• Multiple folders can be selected at one time by holding the Shift or Control keys.

• Click the Add button to add the new inclusion to the Inclusion List.

• Click OK.

To Include a Specific File Extension:

• Select File Extension (File type) from the Type drop down menu.

• Select the specific Volume you want the file type inclusion to apply.

• Click one or more file extensions from the list (Shift and Control work as usual). If the extension you want to include is not in the list, click the “Enter new” entry at the top of the list, and enter the file extension with a starting period followed by the desired file extension (e.g., .123). Enter an optional description of the file extension, and then click OK. Highlight the newly added file extension.

• Click the Add button to add the file extension to the Inclusion List.

• Click OK.

To Create a Custom Inclusion

This option allows the User to create more flexible inclusions than the above Volume, Folder, File, or File Extensions inclusions can.

Custom allows the User to specify specific volume, folder, file names and file extensions, as well as the starting folder or subfolder, and whether it applies to everything below the folder or not.

For example: Include all files with a *.123 file extension but only within all subfolders beneath C:\MyFolder.

To create a custom inclusion:

• Select Custom from the Type pull down menu.

• Choose from the following options from the I want to include pull down menus:

Files

Folders

Volumes

With the file extension (click the List button or fill in the file extension directly)

With the file name

With the full name

From the Folder

From the subfolder

From all folders

From all folders below

From the subfolder and all folders below

Fill in the path to the folder or click the Browse button to select the folder location to include. Choose one of the location options on the left such as My Computer. For My Computer, click the volume you want to include, or double-click a volume to navigate down to the desired sub-folder, then click OK:

From the volume (select the volume from the pull down menu)

From all volumes

And finally click the bottom pull down menu to select the volume to include from.

• Click the Add button to add the custom inclusion to the Inclusion List.

• Click OK.

To Remove an Inclusion from the List

An existing inclusion can be removed from the list by highlighting the inclusion and then clicking the Remove button.

Important Notes:

• Adding items to the Inclusion List will automatically exclude everything not in the list for the selected volume.

• Inclusion List features are not available in the Undelete Desktop Client.

Additional Information

Check for Updates

The first time you run Undelete, it automatically checks to see if a more recent version of Undelete is available. If so, you are given the option to download and install the newer version. When the download screen is displayed, click Run this program from its current location to begin installing the update. Or, click Save this program to disk to save the Undelete update installation package on your computer for later installation. (To install an update stored on your computer in this manner, simply double-click the file you download and follow the instructions displayed.)

You can check for Undelete updates any time you want. Use the Check for Updates option in the File menu to see if a newer version of Undelete is available:

Registering Undelete

If you purchased Undelete directly from the Condusiv eCommerce site, your Undelete Server software is automatically registered and you do not need to do any additional registration steps.

After the Undelete installation is complete, you may be given the option to register your purchase. You can also register Undelete via the Register option in the File menu. Note this will take you to the https://legacy.condusiv.com site.

A Note about Repairing Your Windows System

Performing an emergency repair of a Windows system can possibly change or disable certain system information or services. For this reason, it may be necessary to reinstall Undelete after repairing your Windows system.

A Note About Firewalls

As a normal part of its operation, Undelete acts as a server on your network. If you are running a hardware or software firewall, you may see messages indicating Undelete is trying to act as a server. These messages are expected; you can safely allow these events.

You may also be notified that Undelete is trying to access the Internet. It is important to note that Undelete does not access the Internet (except when you specifically use the Check for Updates feature), but it does use Windows mechanisms that may trigger these alerts from your firewall. Again, these messages are expected and you can safely allow the events.

About the Undelete Service

Undelete is primarily designed as a “Set It and Forget It”® file recovery system. In order to accomplish this goal, it creates a Windows service. The service allows Undelete to run in the background while other applications are running.

After installation, the Undelete service starts automatically each time your Windows system is started. The Undelete service runs all the time, whether or not Undelete is in use. This service consumes negligible system resources. It must be running for Undelete to save deleted files in the Recovery Bin and for the Undelete user interface to operate correctly.

Important Points

Here are several important points about using Undelete:

• When you install Undelete, it will take the place of any other file recovery utilities currently installed on your computer. This includes the Windows Recycle Bin as well as third party products that perform similar functions.

• Where security is of concern, the Recovery Bin Properties can be set to completely erase files that are deleted from the Recovery Bin, using the SecureDelete option.

• Long filenames might be shortened to the DOS 8.3 file naming convention when files are deleted from the Windows command prompt and recovered with Undelete.

• You can right-click a file in the Recoverable Files list and perform a variety of functions, including:

• • Recover… (to Original Location or Somewhere Else)

• • Delete

• • Exclude (Exclude File or Exclude File Type–only available in Server and Professional Editions)

• • View Copies

• • Open

• • Open With (Choose Program)

• In keeping with NTFS file security, you must have sufficient file permissions and ownership to recover a file from the Recovery Bin.

• You can adjust the size of the Recovery Bin(s) on the system via the Settings menu > Properties ribbon icon. If Each drive has its own Recovery Bin has been selected under the Global Settings tab, then the sizes for each Recovery Bin are set under the individual drive tabs. If Use one Recovery Bin for all drives has been selected under the Global Settings tab, then the size of the Recovery Bin is set under the Common Bin tab, along with its full path location.

• By default, when the Recovery Bin reaches the size you have specified, it is automatically partially purged to make room for newly deleted files. For this reason, files that were once stored in the Recovery Bin can become no longer available from the Recovery Bin. This default behavior can be changed in the Recovery Bin Properties Global Settings tab, including disabling a fixed sized Recovery Bin when the Bin fills up.

• If a file of the same name exists in the “deleted” file’s previous location, the “deleted” file is recovered, but with a “version number” added before the file extension. Because of this capability, multiple files of the same name can be recovered.

How to Recover a File Across the Network

So you’ve deleted a file from a network file server (or another computer on your network) and now you need to get the file back. What should you do next?

There are several ways to recover the file, depending on the Undelete edition you are using. (Keep in mind the computer from which the file was deleted must also be running Undelete Server or Undelete Professional.)

If you are using Undelete Server Edition, Undelete Professional Edition or Undelete Desktop Client, you can simply connect to the network folder the file was deleted from using the Connect Network Folder feature described below.

After connecting to the remote folder, you can recover the file as if it were deleted from your local computer. Follow the steps above under “Using the Undelete Server Recovery Bin to Recover Files” for additional information about recovering a file from the Recovery Bin.

How to Search Recovery Bin

Recovery Bins can house many thousands of files so it can be helpful to be able to search a Recovery Bin for specific files when you don’t know which Recovery Bin folder the file(s) reside in.

The Search Recovery Bin feature allows the User to search for files by name and folder location.

The User can optionally narrow the search by:

• Adding the date the files were created or deleted, and/or

• Adding the names of the Users who owned or deleted the file(s)

To use the Search Recovery Bin feature:

• Click the Search Recovery Bin ribbon icon in the Home menu:

• Fill in the Name field with as much of the filename(s) information as possible. Wild card characters (* and ?) can be used if desired:

• Fill in the Location field as the place to start the folder search from. Clicking the Browse button will bring up the folder tree view where you can navigate and highlight a folder to start the search from. If you don’t know what location to start from, choose the root of the volume (e.g., C:).

In most cases it’s beneficial to keep the “Include subfolders in search” check box checked:

To also include the Date the files were created or deleted in the search criteria:

• • Click the Date tab.

• • Check the Include the date the files were created or deleted in this search check box. Select either Files Created or Files Deleted in the Search by drop down menu, and choose either in the last number of days, or between two dates.

To also include the names of the Users who owned or deleted the file(s):

• • Click the Owner / Deleted by tab.

• • Check the Include name of the user who owned the file check box if you want to select the name of the User who owned the file(s) from the Name drop down menu; and/or

• • Check the Include name of the user who deleted the file check box if you want to select the name of the User who deleted the file(s) from the second Name drop down menu.

Once all search criteria has been entered, click the Search button to start the search.

While the search is in progress the User will have the option of clicking the Stop button to stop the search.

Search results will be displayed in the Recoverable Files area.

How to Change the Recovery Bin Properties

Use the Settings menu > Properties ribbon icon to access the Recovery Bin Properties and Settings.

Within the Recovery Bin Properties dialog box, you can manage the settings for individual drive volume Recovery Bins or common Recovery Bins.

This includes:

• Global Settings that apply to all Recovery Bins – Individual Recovery Bins versus a Common Recovery Bin; SecureDelete all files immediately; enable/disable Recovery Bins; sizing rules for Recovery Bins; enable/disable the saving of deleted zero length files; enable/disable Recovery Bin Virus Protection; enable/disable the ability to turn on SecureDelete on purge for Recovery Bins; enable/disable the “Confirm each delete from the Recovery Bin” warning.

• Versions – Enable/disable saving of file versions; specify the number of versions saved per file; specify the file type extensions that will be saved in the Recovery Bin as versions.

• Common Bin – Specify the location of the Common Bin; specify its size; enable/disable feature to purge files older than a specified number of days.

• Individual drive volume Recovery Bin settings – Enable/disable Bins; set Recovery Bin size; enable/disable feature to purge files older than a specified number of days; enable/disable Automatic Wipe Free Space feature.

Global Settings Tab

• Each volume has its own Recovery Bin or Use one Recovery Bin for all volumes – Set whether each drive volume has its own Recovery Bin or whether a common Recovery Bin is used for all volumes.

• SecureDelete all files immediately – Enabling this and clicking OK will cause Undelete to run SecureDelete immediately on all files in all Recovery Bins. This action is not reversible. Once the cycle has completed, even the Search feature will not be able to recover files.

• Enable Recovery Bin on newly detected volumes – This is turned off by default.

• Turn off Recovery Bin on all volumes – There may be times when the User wants to temporarily turn off all Undelete Processing of deleted files. This is the setting to do that.

• Automatically Resize Recovery Bin based on free space – Turned on by default to best support the changing nature of free space on User systems.

• Make Recovery Bin a fixed size – Turned off by default. When enabled, it has two mutually exclusive options: Auto Purge when Bin becomes full and Disable Recovery Bin when Max Size is reached. Additionally, when this is turned on the option to also Display Recovery Bin Full warnings is available.

• Do not save zero length files – Turned on by default. There are times when the Operating System and applications will create a files that do not have any contents in them—such as temporary files. Not saving these files to the Recovery Bin saves time and processing overhead.

• Enable Recovery Bin Virus Protection – Turned on by default.

• Enable Recovery Bin SecureDelete on purge – Turned off by default. Turn on this setting to allow the SecureDelete feature to be available for Individual drive volume Recovery Bins. Note that when this is enabled, all individual Recovery Bins will be set to SecureDelete files from their volumes from that point forward. The SecureDelete feature can be disabled as needed on individual Recovery Bins however.

• Enable Automatic Wipe Free Space – Turned off by default to reduce processing overhead. Useful on secure systems that have to maintain a high level of security for deleted files. The wiping of free space will prevent the Search feature from being able to locate deleted files that are not in the Recovery Bin.

Versions Tab

• Enable saving of file versions in the Recovery Bin – Turned on by default. Allows the saving of designated file types as changes are made to an opened file during Saves.

• Limit each file to – Set to 5 by default.

• Save versions of these selected file types – By default, Microsoft Office file types for Microsoft Word, Excel, and PowerPoint are included, and additional file types can be added as desired.

Common Bin Tab

• Specify the Volume and Full Path where you want the Recovery Bin to be located – When the Use one Recovery Bin for all volumes setting in the Global Settings tab is enabled, the Volume pull down menu and Path fields become available to be set. The Path field needs to have the Full Path to the Common Bin specified.

• Recovery Bin will automatically resize to [X] percent of free space – Defaults to 20 percent, and can be adjusted up to 80 percent using the scroll controls or by changing the horizontal slider control.

• Purge files older than X days – Turned off by default but can be set to the desired number of days. When enabled, defaults to 7 days.

Individual Drive Volume Tabs

• Enable a Recovery Bin on this volume – This setting may be enabled by default if the User did not change the setting during the Undelete product installation. When enabled, saves files deleted from the selected drive so that they can be recovered at some point in the future. This applies to the individual Recovery Bin associated with this drive. This Recovery Bin may also be functioning as the Common Recovery Bin if this drive has been selected as the location for the Common Recovery Bin.

• Recovery Bin will automatically resize to [X] percent of free space – Defaults to 20 percent, and can be adjusted up to 80 percent using the scroll controls or by changing the horizontal slider control. This setting is only applicable when Automatically Resize Recovery Bin based on free space is selected in Global Settings. As the amount of available free space changes on the volume, so will the space used by the Recovery Bin. Undelete will automatically purge older files from the Recovery Bin as necessary.

• SecureDelete files on this volume – When the Enable Recovery Bin SecureDelete on purge setting is enabled in Global Settings this option becomes available to set. When active, it is turned on by default. It will cause the permanent erasure of any file deleted on the selected drive. The deleted file will not appear in the Recovery Bin or the free space of the disk—rendering it completely unrecoverable. Use this feature only when absolutely required, as it does involve a performance hit.

• Purge files older than X days – Turned off by default. When enabled, defaults to 7 days. Use this option to control when files will be purged from the Recovery Bin. If a file in the Recovery Bin is more than the specified number of days old, it will be purged. This setting applies to both Auto-Size and Fixed-Size Recovery Bins.

• Save files deleted from Macintosh shares – Turned on by default. This option causes files deleted from SFM shares to be saved in the Recovery Bin (as long as the file is not on the Exclusion list). When this option is not enabled, files from Windows Services for Macintosh (SFM) shares are not saved in the Recovery Bin. We recommend leaving it enabled unless deletion performance on SFM shares is critical to your operation.

Using SFM, it is possible to make one or more shared folders or disks visible to Macintosh computers on your network. Special actions are required by Undelete to save files deleted from these shares. The actions needed to copy these files into the Undelete Recovery Bin involve more work and time than a normal file deletion, and thus Macintosh file deletions from SFM served shares may take more time. There is no impact to local files deleted from the Macintosh or to files on non-SFM shares on the server.

• Enable Automatic Wipe Free Space – Turned off by default. Useful on secure systems that have to maintain a high level of security for deleted files. Enable this option to keep the free space clean by wiping on a periodic basis going forward.

Auto-Wipe Free Space will overwrite free space on the selected volume with a specific bit pattern, making it virtually impossible to recover any data that may reside in the free space. It leaves the Recovery Bin intact and functioning, and wipes the free space clean.

The wiping of free space will prevent the Search feature from being able to locate deleted files that are not in the Recovery Bin.

Note: Recovery Bin Properties is not available in the Undelete Desktop Client.

How to Prevent Files From Being Moved to the Recovery Bin

The Recovery Bin Exclusion and Inclusion Lists give you very complete, yet flexible control over what files are included and excluded from Recovery Bin processing. You can specify disk volumes, folders, individual files, or a particular file type you want included or excluded. Or, you can create custom inclusion and exclusion rules to fit a wide range of needs.

Exclusion List

Use the Recovery Bin Exclusion List to create a list of directory folders, files, and file types that you do not want to be processed by the Undelete Recovery Bin. When a deleted file (or the folder where it is stored) is excluded from the Recovery Bin, it really is deleted from the disk—not moved to another location on the disk (as other files normally are) when Undelete is running.

One example of a file type you would likely exclude from Recovery Bin processing are temporary files that you really do want to delete. These are often files with a .tmp file extension, but many other extensions are also used, depending on the applications you are running. A number of common temporary file types are excluded from Recovery Bin processing by default.

Typically, when you install an application, a number of temporary files are created, and then eventually deleted by the installation program. Also, compilers and Web browsers often create a large number of temporary files. There may be little chance you will ever need to recover these temporary files, so by excluding them from being processed by the Recovery Bin, the program really will delete them, and they won’t take up Recovery Bin space unnecessarily.

Inclusion List

Use the Recovery Bin Inclusion List to create a list of directory folders, files, and file types that you specifically, and exclusively, want to be processed by the Undelete Recovery Bin.

This is a new feature for this version of Undelete designed to make it easier for Users who want to have the Recovery Bin operate only for specific volumes, folders, files, or file types.

The User will be asked to confirm any entries added into the Inclusion List due to the exclusive nature of the feature.

Important Notes:

• Adding items to the Inclusion List will automatically exclude everything not in the list for the selected volume.

• Exclusion List and Inclusion List features are not available in the Undelete Desktop Client.

How to Push Install Undelete Across a Network

About PushInstall

Use the Undelete PushInstall feature to install or uninstall Undelete Desktop Client, Professional Edition or Server Edition on selected computers throughout your network. Note that you must have valid Undelete licenses for the machines on which you intend to install Undelete.

You must have Administrator access on all the selected computers to PushInstall Undelete to Windows XP and newer Windows Operating systems. If necessary, the PushInstall program will prompt you to enter login credentials for the machine(s) to which you are PushInstalling.

Note: The Undelete PushInstall feature only installs or uninstalls Undelete on machines in the same domain as the Undelete Server from which it is run. In other words, you must use PushInstall within a single domain. For Active Directory systems, it is recommended to use group policy to remotely install or uninstall.

The PushInstall feature establishes a network connection with the selected machines, then installs the selected Undelete edition to those computers. It relies on having the installable Undelete package(s) available to be installed. The first time you use the PushInstall feature, the program attempts to detect the installable files. If they cannot be found, you will see a dialog box prompting you for the location of the installation package. You can use either a CD-ROM or downloaded installation package. Once you choose the Setup.exe file, the installation package is copied to a storage area used by the PushInstall program.

If you try to PushInstall an Undelete version that is not compatible with the target machine, a message explaining the situation is displayed. Messages are also displayed to let you know the status of the installations.

Before the PushInstall operation begins, you will see a message asking you to confirm the version and build numbers of the installable package.

When PushInstalling the Undelete Desktop Client, you also have the option to have an Orientation screen displayed on the remote computer (for your users’ benefit) explaining how to use it. This helps familiarize your users with the Undelete Desktop Client and shows them how to use it to recover their own deleted files from the file server running Undelete.

Running PushInstall

Follow these steps to install or uninstall Undelete Desktop Client, Undelete Professional Edition or Undelete Server Edition to remote computers on your network:

1. From the Windows Start menu, select Programs, then Undelete PushInstall.
2. A welcome screen is displayed. Click Next to continue.
3. If necessary, the PushInstall program will prompt you to enter login credentials for the machine(s) to which you are PushInstalling.Enter a username and password for an account that is a member of the Administrators (or Domain Administrators) group for the domain on which you are installing or uninstalling Undelete.
4. Once the PushInstall process has started, messages are displayed showing you the status of the operation.

How to Connect to a Network Folder

To connect to Recovery Bin content for a network share, select Connect Network Folder from the Tools menu.

When you use this option, a dialog box will open where you must enter some basic information in order to connect to and display a network share.

In the Display as field, enter a name you want displayed in the Recovery Bin tree Folders pane.

In the Path field, enter the network path of the folder to which you want to connect, or click the Browse button to navigate to the folder.
