When working with consultants in setting the system up, we first thought
to snapmirror the production side snavault secondary to the DR site, but
then we started thinking (yea, thinking is hard). In a DR we would have a
snapmirrored copy of production, and, a snapmirrored snapvault copy, but
there would be no tie between them. We want the DR site to "just work".
THis meant we wanted the DR snapvault relationship to be working form the
DR copy of the data. (did any of that make sense?)

I wish I understood snapvault better. It's my understanding is the same
as yours - it's only a qtree level restore. What you would do is run
snapshots on the production volume (hourly, daily, weekly, whatever) from
which individual files could be restored (right click in windows, or, from
the snapshot dir), and, snapvault it to your snapvault filer for big
restores if needed. Individual files could also be copied from a mounted
snapvaulted qtree.

Subject: Can you abandon conventional NDMP backups for SnapVault?
Sent by: "ADSM: Dist Stor Manager" <ADSM-L AT VM.MARIST DOT EDU>
Hello,
Thanks for all the replies!
I've had a pretty bad experience with SnapDiff. We engaged IBM several
times to help us sort out our NDMP backups, and all they could suggest was
to use SnapDiff. So I tested it, and it turns out it cannot be used for
NetApp in cluster mode! It can only be used for NetApp in 7-mode. So there
goes SnapDiff, so we've had to depend on trying to run NDMP. That's why
we're thinking of SnapVault now.
Richard, thanks for sharing your design. It is similar to what we are
considering. Howevever we are thinking of just SnapMirroring the secondary
SnapVault NetApp to the DR site. A couple of questions though:
- How do you do single file restores? As far as I understand snapvault
works at qtree level, so what happens when you need to restore a file?
- Do you do any tape outs with SnapVault? Does it need to be scripted
separately ?
Thanks!
