I was able to take backup with VM Ware option from Netbackup. But the restore job is failing with error 21. When i ran the instant recover command from below was the output.


C:\Program Files\Veritas\NetBackup\bin>nbrestorevm -vmw -ir_activate -C WIN8-Bit
locker -temp_location temp_location_for_writes
Restore image time = 11/26/16 15:57:05
