The error code returned to NW from the VSS framework is very generic so we
can't say from just that information what could be the problem. The most basic
of troubleshooting steps is for the customer to consult the Windows Event
Viewer and find the exact VSS error messages recorded there. Navigate to
Applications and Services Logs. With the VSS event ID in hand, use this web
site to see what Microsoft might recommend to resolve the events:

AH. No, we don't need PIT (Point In Time) recoveries; we always do fulls.
But I frequently see errors relating to VSS in my job logs (even on machines
where the VSS updates have been applied, or - like below - on
Win2008 R2 clients).
Things like:
C:\ 7281:save: VSS snapshot failed with error 0x80042301 -- VSS Backup or
Restore is not in the correct state for the operation, or the writer is not in
the correct state..
C:\ 7284:save: Networker will save the files without the snapshot.
If I do nothing, the problem usually disappears by the next night. Not sure why
it happens, but it doesn't seem to affect the quality of the backups.
So I think I will stick with NMSQL. I have some SQL servers/clusters being
upgraded soon; perhaps I will try out the NMM client on one of those, first.
Thanks
