Using Windows Maintenance Tools on the DPM Server

適用於: System Center Data Protection Manager 2010

In general, you can add the DPM server to your regular maintenance schedule and use the maintenance tools provided in Windows Server 2008. However, you need to be aware of some considerations that apply to a few specific tools when you use them with DPM. Those tools are listed in the following table.

Windows Maintenance Tools and DPM

Windows Tool Considerations

Disk Cleanup: Use to remove temporary files, Internet cache files, and unnecessary program files.

Disk Cleanup is not available for replica volumes and recovery points volumes in the DPM storage pool.

Disk Defragmenter: Use to analyze volumes for the amount of fragmentation and to defragment volumes.

You should not run Disk Defragmenter on disks that are members of the storage pool on the DPM server. Knowledge Base article 312067 explains the issue with Disk Defragmenter as follows:

"The System Shadow Copy provider uses a copy-on-write mechanism that operates at a 16-KB block level. This is independent of the file system's cluster allocation unit size. If the file system's cluster size is smaller than 16 KB, the System Shadow Copy provider cannot easily determine that disk defragmentation I/O is different from typical write I/O, and performs a copy-on-write operation. This might cause the Shadow Copy storage area to grow very quickly. If the storage area reaches its user-defined limit, the oldest shadow copies are deleted first."

For more information about this issue, see the Microsoft Knowledge Base article Shadow copies may be lost when you defragment a volume (https://go.microsoft.com/fwlink/?LinkId=65210).

Chkdsk.exe: Use to check the file system and file system metadata for errors and to display a status report of its findings.

Do not run chkdisk on DPM replica and recovery point volumes. Chkdsk causes the volumes to dismount, and if data is written to the replica volume while the recovery point volume is dismounted, it might cause a complete loss of recovery points.
