Undelete Saves Your Bacon, An In-depth Video Series

by Spencer Allingham 13. May 2019 03:43

Undelete® is a lot more than those simple file recovery utilities that just search through free space on Windows machines looking for recoverable data. Undelete does so much more; protecting files in network shared folders and capturing versions of any number of file types.

If you've ever had to rely on restoring from backup or a snapshots to get a deleted file back, watch now to find out how Undelete makes the recovery faster and more convenient on workstations, laptops and Windows servers.

Undelete, the world’s #1 file recovery software, as a first line of defense in your disaster recovery strategy can save your bacon!

“Undelete saved my bacon.” — Ken C, Cleveland State University

Why are some deleted files not in the Windows Recycle Bin?

Were you aware that the Windows Recycle Bin falls short of capturing all file deletions?

Whilst the Recycle Bin is very quick and convenient, it doesn’t capture:

· Files deleted from the Command Prompt

· Files deleted from within some applications

· Files deleted by network users from a Shared Folder

Undelete from Condusiv Technologies can capture ALL deletions, regardless of how they occur.

“It saved our bacon when a file on my system was accidentally deleted from another workstation. That recovery saved hours of work and sold us on the usefulness of the product.”

“Our entire commissions database was saved by the Undelete program. Very happy about that. We would have lost a week of commissions (over 2000 records easily). We were very grateful that we had your product." Frank B, Technical Manager, World Travel, Inc.

Watch this video for a demonstration of why the Recycle Bin falls short and how the Undelete software can pick up the slack and truly become the first line of defense in your disaster recovery strategy. 

What is Undelete File Versioning?

Have you ever accidentally overwritten a Microsoft Word document, spreadsheet or some other file?

Would it be helpful to have several versions of the same file available for recovery in the Windows Recycle Bin? Sorry, but the Recycle Bin can’t do that.

However, the Undelete Recovery Bin can!

“I'm glad I found yours -- it works very well, and the recovery really saved my bacon!” — John

Watch this video to see a demonstration of how capturing several versions of the same file when they get overwritten can really help save time as well as data.

Searching the Undelete Recovery Bin

Recover deleted files quickly and conveniently with Undelete’s easy search functions.

Even if you only know part of the file name, or aren’t sure what folder it was deleted from, see in this video how easy it is to find and recover the file that you need.

“I would recommend undelete as it has saved my bacon a couple of times when I was able to recover something that I deleted by accident.” — Joseph

Inclusion and Exclusion lists in Undelete

Find out how to use Inclusion and Exclusion Lists in the Undelete software to only capture those files that you really might want to recover and exclude all of those files that you don’t really care about.

Have you ever needed to get a file back that was deleted during a Windows Update? Probably not, so why have those files take up space in your Recovery Bin?

“It saved my bacon a few times.” — Jason

Watch this to see how configurable the Undelete Recovery Bin is.

Emergency Undelete Software

See a demonstration showing how easy it is to recover deleted files, even BEFORE you install the Undelete software from Condusiv Technologies.

Prevent that awful moment of extreme realization when you delete a file that isn’t backed up.

Oh! And if you’ve found this page because you need to recover a file right now, click here to get the free 30-day trialware of Undelete. We hope this helps you out of the jam!

Undelete 11 coming soon – User Feedback Drives New Features

by Gary Quan 4. January 2019 09:38

Soon to be released is a new major version of Undelete. I have been able to preview a pre-release version of this new Undelete and wanted to share the new enhancements. These changes were driven from current Undelete customer feedback looking for further improvement of the product. In a later blog, I will go into each new feature in more detail, but for now, I just wanted to briefly list some of these new features that will be soon available to you.

Ø  New User Interface: Undelete now has a familiar File Explorer-like interface that is easy to navigate, which makes it easy to find and recover deleted files.

o   The interface is also much faster and more responsive than before.

o   A Drag and Drop feature has been added to easily recover local files from the Undelete Recovery Bin.

 

Ø  Expanded File version protection: In previous Undelete editions, the popular ‘Versioning’ feature was limited to just Microsoft Office files. This versioning protection has been expanded to other file types.  This means that if you accidently save a new version of a file with incorrect changes, Undelete can help you go back to the previous version to recover from those unwanted changes.

Ø  Enhance Search Wizard: Expanded search capabilities have been added to help find the user’s deleted files in instances where the user cannot recall the name of the file or where it was located. This includes wild card names search capabilities, plus deleted date ranges, plus who deleted the file.

Ø  Inclusion List: For those users who only want specific deleted folders, file names, or file types to be protected, they can now specify them with this inclusion list capability.

Ø  Cloud Support: The Common Recovery Bin can now be stored or located in the cloud using OneDrive and other hosting capabilities. This has several benefits, including saving space on your local storage, plus protecting these recovery files from security threats like ransomware.

 I look forward to our customers using this new and improved release of Undelete.

Solving the IO Blender Effect with Software-Based Caching

by Spencer Allingham 5. July 2018 07:30

First, let me explain exactly what the IO Blender Effect is, and why it causes a problem in virtualized environments such as those from VMware or Microsoft’s Hyper-V.



This is typically what storage IO traffic would look like when everything is working well. You have the least number of storage IO packets, each carrying a large payload of data down to the storage. Because the data is arriving in large chunks at a time, the storage controller has the opportunity to create large stripes across its media, using the least number of storage-level operations before being able to acknowledge that the write has been successful.



Unfortunately, all too often the Windows Write Driver is forced to split data that it’s writing into many more, much smaller IO packets. These split IO situations cause data to be transferred far less efficiently, and this adds overhead to each write and subsequent read. Now that the storage controller is only receiving data in much smaller chunks at a time, it can only create much smaller stripes across its media, meaning many more storage operations are required to process each gigabyte of storage IO traffic.


This is not only true when writing data, but also if you need to read that data back at some later time.

But what does this really mean in real-world terms?

It means that an average gigabyte of storage IO traffic that should take perhaps 2,000 or 3,000 storage IO packets to complete, is now taking 30,000, or 40,000 storage IO packets instead. The data transfer has been split into many more, much smaller, fractured IO packets. Each storage IO operation that has to be generated takes a measurable amount of time and system resource to process, and so this is bad for performance! It will cause your workloads to run slower than they should, and this will worsen over time unless you perform some time and resource-costly maintenance.

So, what about the IO Blender Effect?

Well, the IO Blender Effect can amplify the performance penalty (or Windows IO Performance Tax) in a virtualized environment. Here’s how it works…

 

As the small, fractured IO traffic from several virtual machines passes through the physical host hypervisor (Hyper-V server or VMware ESX server), the hypervisor acts like a blender. It mixes these IO streams, which causes a randomization of the storage IO packets, before sending out what is now a chaotic mess of small, fractured and now very random IO streams out to the storage controller.

It doesn’t matter what type of storage you have on the back-end. It could be direct attached disks in the physical host machine, or a Storage Area Network (SAN), this type of storage IO profile couldn’t be less storage-friendly.

The storage is now only receiving data in small chunks at a time, and won’t understand the relationship between the packets, so it now only has the opportunity to create very small stripes across its media, and that unfortunately means many more storage operations are required before it can send an acknowledgement of the data transfer back up to the Windows operating system that originated it.

How can RAM caching alleviate the problem?

 

Firstly, to be truly effective the RAM caching needs to be done at the Windows operating system layer. This provides the shortest IO path for read IO requests that can be satisfied from server-side RAM, provisioned to each virtual machine. By satisfying as many “Hot Reads” from RAM as possible, you now have a situation where not only are those read requests being satisfied faster, but those requests are now not having to go out to storage. That means less storage IO packets for the hypervisor to blend.

Furthermore, the V-locity® caching software from Condusiv Technologies also employs a patented technology called IntelliWrite®. This intelligently helps the Windows Write Driver make better choices when writing data out to disk, which avoids many of the split IO situations that would then be made worse by the IO Blender Effect. You now get back to that ideal situation of healthy IO; large, sequential writes and reads.

Is RAM caching a disruptive solution?

 

No! Not at all, if done properly.

Condusiv’s V-locity software for virtualised environments is completely non-disruptive to live, running workloads such as SQL Servers, Microsoft Dynamics, Business Information (BI) solutions such as IBM Cognos, or other important workloads such as SAP, Oracle and the such.

In fact, all you need to do to test this for yourself is download a free trialware copy from:

www.condusiv.com/try

Just install it! There are no reboots required, and it will start working in just a couple of minutes. If you decide that it isn’t for you, then uninstall it just as easily. No reboots, no disruption!


Help! I hit “Save” instead of “Save As”!!

by Gary Quan 19. June 2018 06:30

Need to get back to a previous version of a Microsoft Office file before the changes you just made?  Undelete has you covered with its Versioning feature.

Have you or your users ever made some changes to a Word document, Excel spreadsheet, or a PowerPoint presentation, saved it and then realized later that what was saved did not contain the previous work? For example, and a true story, a CEO was working on a PowerPoint file he needed for a Board of Directors presentation that afternoon. He had worked about 4 hours that morning making changes and he was careful to periodically save the changes as he worked. The trouble was the last changes he saved had a large part of his previous changes accidentally overwritten.  The CEO then panicked as he just lost a majority of the 4 hours of work he just put in and was not sure he could redo it in time for his presentation deadline. He immediately called up his IT Manager who indicated the nightly backups would not help as they would not contain any of the changes he made that morning. The IT Manager then remembered he had Undelete installed on this file server. This was mainly to recover accidentally deleted files, but he recalled a Versioning feature that would allow recovery of previous versions of Microsoft Office files. He was then able use Undelete to retrieve the previous version of the CEO’s PowerPoint presentation and recover the work he did that morning. The CEO was extremely happy, and the IT Manager was a ‘hero’ to the CEO!

Another very common scenario is users making edits to original files and then selecting “Save” instead of “Save As” and then the original files are now gone. As an example, a customer had a budget file in Excel and several people had accessed it throughout the day. At some point, someone had inadvertently made multiple changes to it for his department, including deleting sections that were not relevant to his department all the while thinking he was working in his own Save-As copy. Boy, were the other department heads upset! The way our IT Admin customer tells the story it sounded like a riot was about to erupt! Well, he swoops in just in time and recovers the earlier version in minutes and saves the day. We hear stories daily about Word document overwrites that IT Admins are able to recover the previous versions of in just a few minutes, saving users hours of having to recreate their work.

While the most popular functionality of Undelete is the ability to recover accidentally deleted files instantly with the click of a mouse, the Undelete Versioning feature is certainly the runner up, so we wanted to remind users, or prospective users, that it’s also here to save the day for you, too.

The Undelete Versioning feature will automatically save the previous versions of specific file types, including Microsoft Office files. The default is to save the last 5 versions, but this is settable.  Undelete then allows you to see what and when versions were saved and are then easily recoverable. A vital data protection feature to have.

If you already have Undelete Server installed on your file servers, check out the Versioning feature. If you have any of your own “hero” stories you would like to share, email custinfo@condusiv.com

If you don’t have Undelete Server or Undelete Pro yet, you can purchase them from your favorite online reseller or you can buy online from our store http://www.condusiv.com/purchase/Undelete/

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.
