Defrag and RAID: We need this on every server

by Colleen Toumayan 29. July 2009 10:50
Here is a cool success story I thought I'd share:  “The deployment process was exceedingly easy.  Made the purchase, downloaded and installed the software - watched response times drop.  Pretty nice over all. Diskeeper is exceeding my expectations. We had definite performance problems caused by heavy amounts of fragmentation. During the first two hours after installation we saw a significant improvement in access and delivery perceived timings.  This was a big surprise for us. The web application that runs on all of our servers was responding faster, pages popped a little quicker and the time between pages was reduced enough to notice without a stopwatch.   The servers are relatively standard Dell PowerEdge rack servers, running 3-6 drives in a RAID 5 configuration.  Unfortunately I don’t have timing or supporting data for comparison and analysis.   I didn’t really think that we would see a noticeable improvement after adding Diskeeper to the servers; it was more of a preventative maintenance issue for me. But on the databases host servers, we saw query times drop rapidly.   Since changing pages in our application can require dozens (or hundreds) of database calls, a small increase in the database performance results in a significant difference for the application.  Combined with a slightly faster access time for web resource files, it was a very positive change for server performance all around. Diskeeper has been moved from the optional utilities list, to the required utilities list for all of our production server deployment.   We are also recommending Diskeeper for our mid-to-high volume enterprise clients for their own hardware.  When the money-counters notice a difference dramatic enough to say, ‘We need this on every server’, something good has happened!”  Greg Porterfield, Pragmatic SoftwareSolutions Engineer/Architect 



Undelete Tips and Tricks - Setting up "versioning" for new file types

by Michael 19. June 2009 08:47

As a filter driver, Undelete captures everything (except those files/file types explicitly excluded). One of the advanced features of Undelete is the ability to organize previous versions of Microsoft office files into a common recovery location and remove all the wacky characters (~$, .wrl, etc...) normally associated with temp and older iterations of these files. This feature, called "versioning", supports a very intuitive method to easily locate, preview, and recover these previous versions (ex. Microsoft Word document, Excel Spreadsheet, etc.) which may have been overwritten. The feature is nicely integrated with Windows Explorer so you can easily right-click a file and select to view the versions.

We heavily test and officially support the predefined files listed: .doc, .docx, .dot, .htm, .html, .mht, .mhtml, .pot, .pps, .ppt, .pptx, .rft, .txt, .xls, .xlt, .xml; however a user may want to turn on this feature for another file type other than the default provided types. The data below will show you how to add other types, by file extensions. Please note this is a use-at-your-own-risk trick, and involves editing the Windows registry. And, also note that this workaround may not work correctly for all applications due to the manner in which some applications save their files.


For example, you may work at a design company and use AutoCAD and would like to turn on versioning for your CAD files. AutoCAD saves files with an extension of .dwg.

Again, to perform this workaround, you will need to edit the registry. Please note that an incorrect entry in the registry could damage your operating system and make your computer so it will not boot. Follow the instructions below to perform this workaround. 

To start regedit, select Start – Run and enter: regedit               

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Diskeeper Corporation\Undelete\FRBin and edit the VersioningExtension key to add the file type which you want to use versioning on. Following is a screen capture of the registry key.   

Go to HKEY_LOCAL_MACHINE\SOFTWARE\Diskeeper Corporation\Undelete\FRBin and edit the VersioningExtension key to add your file extension followed by OK.  (For the AutoCAD example, you would add .dwg which is entered above.) Once this is complete, exit regedit and restart your computer for the changes you entered to take affect.
