Since a few years we are using DPM to backup our servers but since some time the system state of the server where DPM is installed started to fail.
I was trying to do system state backup using command line windows backup:
wbadmin start systemstatebackup -backupTarget:C:
and it fails every time with different error (last 5 tries):
1. Error in backup of C:\Windows\winsxs\Manifests\x86_microsoft-windows-w..pdateclient-activex_31bf3856ad364e35_7.6.7600.256_none_09f272fb52ab0c3f.manifest during read: Error [0x80070002] The system cannot find the file specified.
2. Error in backup of C:\Windows\System32\msmpeg2vdec.dll during write: Error [0x80070002] The system cannot find the file specified.
3. Error in backup of C:\Windows\System32\catroot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\Microsoft-Windows-WinMan-WinIP-Package-TopLevel~31bf3856ad364e35~amd64~~7.1.7601.16398.cat during read: Error [0x80070015] The device is not ready.
4. Error in backup of C:\ during read: Error [0x80070005] Access is denied.
5. Error in backup of C:\Windows\System32\ActionCenter.dll during write: Error [0x80070002] The system cannot find the file specified.
That's a Windows 2008 R2 server with DPM and OM servers installed.
The system state backup was doing fine for 2 or 3 years and suddenly it just stopped.:/
