I am having a problem backing up a 2008R2 system state with DPM 2010. I
created the registry key/entry indicated in KB944530, rebooted, and the
system state backup still fails in DPM. The error I get in the App Log of the
server being protected is..
Event ID 546
The backup operation attempted at '???2010???-???01???-???06T17:07:41.711891500Z' has
failed to start, error code '2155413599' (%%2155413599). Please review the
event details for a solution, and then rerun the backup operation once the
issue is resolved.
Performing a system state backup LOCALLY on the 2008R2 server works fine
using this command....
wbadmin start systemstatebackup -backuptarget:C:
Any help would be much appreciated, thanks.
