Delete VM directory task in recover operation using Copy (NetBackup) may fail.
In some cases the 'Delete VM Directory' task in recover operation using Copy (NetBackup) may fail due to the disks from that directory are attached to the Replication Gateway. But the overall recover operation does not fail and it should get completed successfully.
Since the original folder is not removed the restore operation from NetBackup primary server creates the different folder with different name. After above situation , any remote recover operation using Copy (NetBackup) to same datacenter without executing the resync/repair operation in between might create new folders and older folder are not deleted.
Workaround:
It is recommended that after every restore operation the resync/repair should be executed to reconfigure the broken replication and to avoid such folders pile up.
