Sometimes we may face errors for DPM trying to backup the client. DPM depends on the clients Volume Snapshot Service also known as VSS.
To check if the VSS is stable, in the designated protected computer, from the command prompt (if admin privilege), key in the command as shown :
|C:\> vssadmin list writers|
The listing shown below as example :
Restart the VSS services either from the Services or reboot the computer.
Thank you and hope this helps.
