Guys,
Has anyone ever tried to do a snapmirror to tape of a volume, then you retrieve it onto the destination. Then can you do the next snapmirror update for the volume to tape as well?
The idea is that it takes so much time to write and read 10Tb of tape, not even counting the FedEx across country time, that it might make sense to also write the next snapmirror update to tape as well.
God knows I'm tempted to try this...

John,
I believe you're asking if it's possible to do an incremental SnapMirror update to tape.
Currently that isn't possible. Every SnapMirror to tape is a full backup.

We have used LREP to initialize huge snapmirror sources. Though we haven't used tape to do it - we have used SATA drives. LREP breaks down large areas into 2G chunks. Then you can compress those files and write them to disk. Send them out to the destination site. Uncompress them out to a staging area. Then use LREP to put it back together again.
It is a long process but for our large applications repository (4T) that had to be snapmirrored around the world, we were successful getting that initialized to all our sites. Good luck. C-
