Will,

One way to answer your question is with "bpimagelist -media"; read the man page for an explanation of the options.  If you provide the appropriate qualifiers (client, dates, etc.) to focus the search, you find what media would potentially be needed for the restore.  Ed's advice is better in that kicking off the restore is likely to require fewer tapes as the restore may specify down to files while bpimagelist doesn't allow that.

Ed omits a few of the details on the mechanics of watching for jobs needing media, suspending and alerting.  The attached script shows a means of doing that.  It should be seasoned to taste and then called from cron on 5 minute intervals.

I'm curious as to what everyone is using for the "Images on Media" process?  If you need to do a restore outside of the "tape reports" window, how do you determine which tapes are requested from Iron Mountain or whatever off-site provider you use to perform the restores?

Our standard way is to kick off a restore, let it determine which tapes are needed, suspend the restore, call back tapes, and then resume the restore.
This usually works well but you have to be careful if there any images on DSSUs that could get deleted between the initial restore and when it's resumed.

There are ways to preview the restore to tell you which tapes are needed but why bother with a preview - you either need the restore or you don't.
