For offsite, use a remote filer and SnapMirror. We manage 39 TB of data on NetApp here. We use a local cluster and a remote cluster. The retention is hourly SnapShots for 24 hours and daily SnapShots for 35 days. SnapMirror runs asynchronously at least once an hour over a GB Ethernet to the remote site. We run NDMP backups at the remote site "just in case", but meet our RPO and RTO requirements with the SnapShots. SnapShots take TSM out of the picture for these backups and have erased our former biggest headache, backing up millions of small files. Orville L.

We have 20+ filers with a total of 9 and 15TB of home and common folders. The problem is when the Filer admins decide to move or split volumes which give us a new full backup... And after some time it will be harder to track data down, where was data stored etc. Currently we backup the qtree ie. on NetApp \\Filername\w0\c00. If the volume gets full and we need to split the data between \\Filername\w0\c00 and \\Filername\w0\c01. However, all (common) folders have DFS links so I can backup ex.\\Filername\w0\c00\Proj. This will give me some 10000 filespaces. But I wont need to worry about the splits/moves. So my question is, how do you handle backup on large filers and data moves? If any, best practise?
