What I did here is not the second drive with the changer at all -- I change
that tape by hand twice a week, and use it to generate an archival level-0
backup  (stored in the tape safe) for long-term storage.  I can use the
tapes in the changer (on drive 1) to restore any file system to any day in
the previous 20 days (since I have a 20-slot changer) and then can restore
to one-week granularity for any week in our tape safe (which goes back two
years).

I know it's not using both tape drives WITH the changer exactly, but it
works well for our needs.
