Well, I've never had the resources to try this, but it might work. Contract
for bucket loads of disk at your disaster site, enough to restore your
critical nodes' primary pool, and restore the copypool to the diskpool using
the maxpr switch to get multiple processes to speed the restore.
Noncritical nodes can wait on tapes. Your critical nodes can then restore
quickly and simultaneously from disk.
Note, if anybody has the funds for that, please don't tell me as it would
make me too darned jealous. Any thoughts on feasability, other than cost?

If you have 20 tape drives, and you're trying to recover many clients,
you'll probably run into this:
Restore of system A has tape volume 0001 mounted;
Restore of System B ALSO needs volume 0001, so it hangs.
If you collocate your copy pool, this shouldn't happen. But collocating
your copy pool is not recommmended.
Anyone have a good solution for this problem?
