we have some big HyperV servers. They are backed up with NMM 3.0.1.2.280.

On one HV server always the same guest vm fails. We only get an generic error message: The code is: 0x800423f3.

There are no messages in the eventlogs of HV server or guest. The HV server was already rebooted.

What could be the reason why the VM backup fails?
