I can find many information on windows defrag, which was build from diskeeper, but I can't find anything similar for Windows Windows Disk Defragmenter does not include all the features available in the full version of Diskeeper but it still work well for basic needs.
So, if you require advanced features for disk defragmentation, you should use Diskeeper from Diskeeper Corporation. If there is any free space at all, Defrag will make an attempt to defragment the volume. For technical information about the Windows Disk Defragment tool in Windows Server R2, you can just refer to Windows Server because there are just limited improvements between disk defragmentation in Windows and that in Windows R2.
For Windows Server the built-in scheduled task for defragmentation is not enabled by default. It is a serious misconception to think one should wait until performance is overwhelmingly poor to run defragmentation. The resul t of this reactive approach is a help desk call proceeded by weeks of reduced productivity.
While a casual home user may manually kick off defrag when he feels his PC is sluggish, in an organization, this costs significant time and money. Simply, this is not an option for enterprise servers. Fragmentation occurs with most file writes. Waiting a week, or even a day, to defragment means users have to operate with reduced performance. Those delays are quantifiable and add up when viewed from a broader business productivity perspective.
In addition to performing the same functions as the graphical version of Check Disk, the command prompt version also provides more detailed disk analysis and repair reports.
The chkdsk utility accepts a number of command line options which govern the tasks performed during execution. These options are outlined in the following table:.
To perform a disk analysis without correcting any errors, simply enter chkdsk at a command prompt together with the drive designator of the drive to be analyzed the following output is the result of running chkdsk on an NTFS volume:.
Disk fragmentation occurs over time as files written to clusters spread over a wide area of a disk volume. As such it is considered good practice to regularly monitor, and when necessary, defragment disk volumes. One method for performing this task is to use the Disk Defragmenter tool which is accessed by right clicking on a disk volume in Windows Explorer or the Disk Management interface in Computer Management and selecting Properties.
In the properties dialog, select the Tools tab and click on Defragment Now This will display the initial screen of the Disk Defragmenter as illustrated in the following figure:. The tool will perform a scan of the selected volume and report whether a defragmentation is recommended and in the above example it is recommended. Click on Defragment now This will cause the drive selection dialog to appear.
Select one or more disks to defragment from this dialog followed by OK to trigger the defragmentation process. As each selected drive is defragmented the progress will be displayed together with a button providing the option to cancel the process.
Windows Server R2 also provides the option to automatically defragment disk drives as a background task. This is scheduled in the Disk Defragmenter tool which can be accessed either from within Windows Explorer or Disk Management as outlined above. Go to Solution. Defrag is useful and desirable on a physical server, and as mentioned above, a pain in a virtual environment.
If you haven't set up your R2 server with a contiguous fixed nonmanaged size page file, not defragging will inevitably result in a hugely fragmented page file which will impact paging and system performance. The one time I do a defrag in a virtual environment is as the final step to preparing a virtual machine template, but that's probably going a bit overboard. View solution in original post. On Windows 7 VDI the first thing you should do is disable defrag in the virtual desktops.
XP doesn't have a background defrag task by default. As for the server: if you're on Hyper-V Server then I don't know if you even can defrag? There's probably a command-line way to do it, although I would think it's most important to defrag the storage where all the virtual hard disk files are stored, more so if you're using local storage. Not much would be my guess. We've also found that vSphere hosted thin provisioned VDI desktops will bloat up to full disk size with the defragmenter turned on, and if I remember correctly, they don't even recover any space if you do a storage vmotion to thin provisioned format.
It's like the defragmenter "touches" all the space in a way that makes it look like it has data - at least for purposes of thin provisioning.
