EV Backup - NAS based Partitions/NDMP
We are running EV8, and have recently moved our EV partition from local storage to a NAS, with Netbackup as the backup solution. Previously, the archive bit was being set by Netbackup and all was functioning swell - but since we've moved the data, the safety copies aren't being purged, as the NAS is being backed up via NDMP and has no mechanism to flip the archive bit.
I understand that a trigger file can be used, but I am unsure how/when that should be created. Should that be a function of the NDMP job?? Would the Netbackup EV agent alleviate this??
Considering that we do pretty frequent snapshots (4x daily) on the NAS volumes, and daily backups to tape - are safety copies even necessary?
Thanks in advance!
