DPM 2012 system state backup failed with error 2033.

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.
