How to Recover Lost or Deleted Files BEFORE Resorting to Outsourced Data Recovery

by Gary Quan 1. November 2017 05:46

Here’s a nightmare scenario…a user accidentally deletes irreplaceable or valued files from a network share, and there is no way to recover the data because:

>The file was created or modified then deleted AFTER the last valid backup/snapshot was taken.

>There is NO valid backup or snapshot to recover the data.

>There was NO real-time recovery software like Condusiv’s Undelete® already installed on the file server

>Sending the disk to a professional data recovery center is COSTLY and TIME-CONSUMING.

What do you do? Well, you may be in luck with a little known feature in Condusiv’s Undelete software product known as “Emergency Undelete.” On NTFS (New Technology File system) formatted volumes, which is the default file system used by Windows, there is an unfamiliar characteristic that can be leveraged to recover your lost data.

When a file gets deleted from a Windows volume, the data has not yet been physically removed from the drive. The space where that file data was residing is merely marked as “deleted” or available for use. The original data is there and will remain there until that space is overwritten by new data. That may or may not happen for quite a while. By taking the correct steps, there is an extremely good chance that this ‘deleted’ file can still be recovered. This is where Emergency Undelete comes in.

Emergency Undelete can find deleted files that have not yet been over-written by other files and allow you to recover them. To increase your chances of recovering lost data, here are some best practices to follow as soon as the files have been accidentally deleted.

1. Immediately, reduce or do away with any write activity on the volume(s) you are trying to recover the deleted files from. This will improve your chances of recovering the deleted files.

2. Get Condusiv’s Undelete to leverage its Emergency Undelete feature.  Emergency Undelete is part of the Undelete product package.

3. REMEMBER: You want to prevent any write activity on the volume(s) you are trying to recover the deleted files from, so if you are trying to recover lost files from your system volume, then do one of the following:

a. Copy the Undelete product package to that system, but to a different volume than the one you are recovering lost files from. Run the Undelete install package and it will allow you to run Emergency Undelete directly to recover the lost files.

  

b. If you do not have an extra volume on that system, then place the Undelete product package on a different system, run it and Emergency Undelete will allow you to place the Emergency Undelete package onto a CD or a USB memory stick. You can then place the CD/Memory stick on the system you need to recover from and run it to recover the lost files.

 

 

Now if the lost files do not reside on the system volume, you can just place the Undelete product package on the system volume, run it and select to run Emergency Undelete directly to recover the lost files.

4. When recovering the lost files, recover them to a different volume.

These same steps will also work on FAT (File Allocation Table) formatted storage that is used in many of the memory cards in cameras and phones. So, if some irreplaceable photos or videos were accidentally deleted, you can use these same steps to recover these too. Insert the memory card onto your Windows system, then use Emergency Undelete to recover the lost photos. 

Emergency Undelete has saved highly valuable Microsoft Office documents and priceless photos for thousands of users. It can help in your next emergency, too.

Undelete Can Do That Too?

by Gary Quan 30. August 2017 04:46

You may have already heard countless customers tout the file recovery features of Condusiv’s Undelete® and how IT Pros use it as a recycle bin on file servers for real-time protection, so they don’t have to dig through backups to recover deleted or overwritten files. Although this is Undelete’s primary function, Undelete provides more than just this. 

What most people do not know is that Undelete also provides features to keep your data secure and visibility into who deletes files from file servers.

When a file is deleted, many assume that file data is now safe from being seen by others. Not so fast. When data gets deleted on a Windows volume, the data does not get removed. The space where that file data was residing is just marked as available for use, but the original file data is still there and will remain there until that space is overwritten by some other file data. That may or may not happen for quite a while. This means, that ‘deleted’ file data could still be potentially read. 

So, what do you do if you really want your file data gone when you delete it?  Undelete has the answer with two features. The first feature is “SecureDelete.”  When a file is deleted, SecureDelete will first over-write the file to help ensure it is unrecoverable. In fact, this is done by overwriting it with a specific bit pattern specified for this purpose by the U.S. National Security Agency (NSA) for the Department of Defense (DOD).  The second feature is “Wipe Free Space”, which will overwrite any free space on a selected volume, using the same specific bit patterns as SecureDelete to clear out any previously written data in that free space.

Now, with these two features, when you delete a file, you know it is now virtually impossible to read/recover any of that data from that volume.

Along with file security, there are customers using Undelete as another precautionary security: check how many files are being deleted from file shares and by whom. If they ever detect an abnormal, substantially high number of files being deleted, that raises a flag for them to investigate further.

Although Undelete is usually purchased to recover files, others use it to securely delete files and track back any deleted files to the person who did it.

I Have Backups and Snapshots, So Why Do Condusiv Customers Use Undelete®?

by James Fields, Director of Customer Support 10. May 2017 09:57

Backups and snapshots are used by enterprises to recover data sets in the event of system failure. But how about individual files on file servers? Often times they are accidentally deleted by users or overwritten.

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.

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 recycle 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 MS Office 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. 

Last month, 53 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”

Help! I deleted a file off the network drive!!

by Robin Izsak 31. October 2013 08:01

What if the recycle bin on your clients could be expanded to include file servers? And what if you could enable your users to recover their own files with self-service recovery? You would never have to dig through backups to restore files again, or schedule incessant snapshots to protect data.

One of the most persistent—and annoying—help desk calls is to help users recover files accidentally deleted off network drives, or support users who ‘saved over’ a PowerPoint they need for a meeting—in 15 minutes.

There are some pretty serious holes in true continuous data protection: First, any data that was created between backups might not be recoverable. Second, who wants to dig through backups anyway? Third, you’d have to schedule an insane amount of snapshots to protect every version of every file. Fourth, the Windows recycle bin doesn’t catch files deleted off a network drive, which is how most of us work in the real world—networks, clouds—not local drives.

Check out our latest guide that explains the gap between backup and the Windows recycle bin, and how to bridge that gap with Undelete® to ensure continuous data protection and self-service file recovery.

Meet the recycle bin for file servers. You’re welcome.

The Next Generation of Real-time Protection and Instant Recovery Software

by Alex Klein 4. September 2012 04:00

Today we announce the worldwide release of Undelete 10 – our real-time data protection and instant data recovery product. With just a touch of a button, Undelete instantly recovers files from Windows servers and workstations – even files that were deleted before Undelete was installed.

Enterprise IT and data have grown immensely since Condusiv first introduced Undelete over 14 years ago. Regardless of the Windows OS you’re running, whether it be a physical or virtual environment – Undelete is the one piece of software your company can’t afford to be without and can truly turn your IT department into a team of heroes.

“I came by Undelete when we had a user delete a whole department worth of files”, says Eric Tremelling, who’s the IT Manager at The Legal Aid Society of Palm Beach County. “It did recover all the files for the whole department.  I was so impressed that I purchased the Undelete Server edition to avoid future problems.  In my opinion, Undelete is one of the best programs we have and saves me lots of potential headaches.” 

“We use a backup system that does nightly backups to tape.  If something is deleted from the file server by mistake I have to go back to the tapes then pull the correct tape then run a restore on the file, provided there was no corruption or problems with the backup tape.  Another issue was that the deleted file could be gone before anyone noticed it was missing and I may not still have a backup that old to recover from.  Furthermore, if the file was created during the day before the backup runs at night, it would be gone because it never got backed up yet. The software has gotten us out of many jams”

 

Have an Undelete story to share? Leave a comment below – we’d love to hear from you!

Undelete 10 features

  • New One-button Search for Recent Files, which allows the user to locate a file deleted within a 24-hour period or one week period with one click.
     
  • New Search Wizard, a single pane view that provides fast and easy way to find a lost file.
     
  • New Dynamic User Interface for ease of use, quality of experience.
     
  • Undelete 10 Server - Protects server files including those deleted by network clients from a centralized management console.
     
  • Undelete 10 Desktop Client – Allows connected laptops, workstations and VMs to recover their own files from remote Undelete 10 Server recovery bins.
     
  • Undelete 10 Professional – Protects locally stored files and allows files to be recovered from remote Undelete Server recovery bins.
     
  • Undelete 10 Home – Provides comprehensive protection of locally stored files.

When a file is deleted, it is automatically captured and stored in the Undelete Recovery Bin. Undelete 10 captures all the files the Windows Recycle Bin misses, such as those deleted from shared network folders, deleted from commonly used applications, deleted by the Windows command prompt, or replaced when newer versions of a file are saved. Also, if a file is modified several times between a backup or shadow copy, it will not be saved. With Undelete, these file versions will be saved and are recoverable.

The Server, Professional and Client editions of Undelete let you see the contents of Recovery Bins on remote computers like file servers, allowing IT or users to recover their deleted files in seconds anywhere across the network with a single click of a button. It’s no longer necessary to spend hours searching backup tapes or Windows Shadow copies when a user accidentally deletes a file from the server.

Undelete can also restore files previously purged from the Recycle Bin or the Undelete Recovery Bin – even if they were deleted before Undelete was installed

Condusiv Undelete 10 “Set it and Forget It”® file recovery system runs on all Windows platforms, including those on VMware and Microsoft Hyper-V environments. Undelete 10 also supports Exchange, SQL, or SharePoint. 

Undelete 10 Server edition supports Windows Server 2008/2008 R2, Windows Server 2003,  Windows XP, Windows Vista, and Windows 7.

Undelete 10 Client, Professional and Home Editions support Windows XP, Windows Vista, and Windows 7.

In compliance with corporate governance or governmental regulatory requirements for secure data deletion, Undelete provides an electronic data shedder: SecureDelete® 2.0. Using a bit pattern specified by the National Security Agency (NSA) for the Department of Defense, SecureDelete not only deletes a file but overwrites the disk space the file previously occupied making it virtually impossible for anyone to access.
