I've got one other use for backupsets: for the big restores.
We've got a ~400 GB server (mail store for central IMAP service at UF) that
we're setting up to have many virtualmountpoints, each of which will
eventually hold ~10GB. (actually ~100GB filesystems)
In this situation, tape "stutter" and re-seek can be a major constituent of
the restore time. To minimize this, we plan:
have a FILE device class available with space ~ 40G + (or know where we'd
get one if the hammer dropped)
2) GEN BACKUPSET NODENAME mail01 devc=filefoo
GEN BACKUPSET NODENAME mail02 devc=filefoo

generating the backupset for the next one.
