I've got a Windows Server 2012 Essentials server that backup fails on start. I am however able to run a system state backup with command:
wbadmin start systemstatebackup -backuptarget:D:
If I try to backup C: drive with this command:
wbadmin start backup -backuptarget:D: -include:C:"
It fails right at start with wbadmin giving this output at the end:
The Windows Backup engine could not be contacted. Retry the operation.
The RPC server is unavailable.
The only Event Viewer errors I have to go by are:

Any thoughts on this?
