To backup sharepoint from DPM 2012 you willl first have to install DPM agent. Then run %program files%\Microsoft Data Protection Manager\DPM\Bin\
When asked fore WSSCmdletsWrapper user enter your farm administrator.
If you get an error :
Then the user you have logged on to the server with does not have the right permissions on the SQL instance.
In some cases DPM agent installed and pointed to the wrong drive as temp drive. You will get an error 2033
“DPM encountered an error while performing an operation for F:\WindowsImageBackup\ on server.test.local (ID 2033 Details: The system cannot find the path specified (0x80070003))”
This can be solved by editing DPM PSDatasourceconfig.xml file. The “FilesToProtect” entry contains the incorrect value.
Got this error on “Computer\System Protection\Bare Metal Recovery” and “Computer\System Protection\System State” , turned out I had forgotten to install windows feature “Windows Server Backup Features” on the client.
