Error 2015/12/22 14:18:56 46 Data Plugin UK3-MCSR01 Error creating volume snapshot(s): VSS_E_OBJECT_NOT_FOUND
Ran backup job with trace enabled. On checking the trace it was found that there were 2 volumes being snapshotted for backup as we see below drives C:\ and E:\ . On investigation we saw that the server only had the 1 drives C:\.
Checked selection set of the backup and we could see that drives c:\ and drive E:\ had been selected but the E:\ drive was greyed out meaning the drive was no longer visible to NetVault.

Drive E:\ was selected but the drive was no longer physically attached to the server being backed up and NetVault was attempting to snapshot the volume that was no longer there.
Modify selection set and deselect Drive E:\ that was no longer attached to the server.
