Not easy to answer, because it depends on a) the number of files on the specific tape (database intensive!) b) the amount of bytes on the specific tape (IO intensive)
We have a similiar environment and a MOVE DATA of a full tape takes a minimum of 30-45 minutes, and some tapes (with more than 100.000 files and compressed 100 Gb on it) takes 3 or 4 hours. So it's not easy to answer.....

When all of your files are on the diskpool, your restore will complete without any Media Waits.....

I manually kick off a base backup to a "spare" TSM server on Friday night so when the call comes in (over the weekend) to restore the servers, I restore from a relatively quiet TSM server. I'm not contending with the production backup cycle. The problem: This backed up data gets migrated to tape prior to my restore. Invariably, multiple servers' data ends up on one tape. i.e. only one server can restore at a time. The question: Is there a way to direct the backup data of a particular server to a specific tape so I can run multiple restores from multiple tapes at the same time? This is killing me... Good suggestions would be appreciated. Regards, Joe
