I believe this is the best forum to ask this question. I have got 2 NetApp storage's: One on the Head Office and another on the DR site, which is basically storage to storage Replication with snapshots enabled. At present we don't take any kind of backups on the tapes or other drives. Is this a good practice? Do I have to still take the backups on the tape drives even though we have a DR site from where we can recover our data?
