Hi Jim,

AFAIK you can do it using 2 methods:
1. Move Nodedata <NodeName> fromstg=CurrentSTG (This will consolidate
all of the node's data from across the STG to as few tapes possible)
2. Move Nodedata <NodeName> fromstg=CurrentSTG ToSTG=Diskpool
Maxpr=<maxdrives> (This will move all the data to your Diskpool, just
make sure the diskpool doesn't migrate the data out before the restore)

I have found that even if you move the data to 1 or 2 tapes the restore
- especially if theres a lot of files - still tapes quite some time.  I
use the Diskpool option and it works great

Subject: [ADSM-L] Pre-fetching a restore?

Hi folks,

I'm working on our internal "late night admin guide," and one of the
things I'm thinking of is how can I get TSM prepared to do a restore.

Here's what I mean: let's say I know that there is going to be some
filesystem maintenance on a client.  Since we've been burned by that
kind of operation in the past, I'd like TSM to prefetch the appropriate
data from tape and have it ready to go (on disk) for a restore.

Archives would do the trick except that uses the client, potentially
during business hours.

Backupsets look like they might work but they're kind of rigid... can a
backupset be restored followed by restoring the latest incrementals?  So
I could create a backupset on Friday before the procedure on Saturday,
and then be able to restore the incremental we took before beginning the
disk operation after that?

Am I out of my tree?  Do people do this?

Thanks,

--Jim
