5.0 does a bit more than that.  When a disk staging unit gets full, it
will suspend the backup, write the disk to tape, and resume the backup.
It is also smart enough to realize that when you're doing a restore, if
the data is still on disk (it's not deleted unless it has to be, even if
the data has been copied to tape), then the restore will take place from
disk and not tape.
