Hello. We're trying to backup a VM running on a host (host-level backup). The operation always fails in DPM with the following error:
'An unexpected error occurred while the job was running. (ID 104 Details: The filename, directory name, or volume label syntax is incorrect (0x8007007B))'
Consistency check/reusme backup always ends up with this error. Removing the protected member and recreating it fails too.
This is the only VM for which the backup is failing. It's running Linux OS. VM doesn't have any checkpoints (even the hidden backup ones). All VSS writers on the host are in stable/no error state.
Monitoring the DPMRACurr.errlog on the host gives some insight, but no hints on how to solve this:
(first there's a production checkpoint creation failure, which is to be expected, followed by successful crash-consistent checkpoint creation)

(then there are more messages, some errors - not of consequence in my opinion, but later there are these errors):
