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.

Perhaps add another configuration, use the second drive as
your tapedev
parameter and change the first and last slot number in your
changer conf
file. So first conf will have slots 1-15 and second conf will control
16-30. Have them backup different filesystem. Althought I
dont know if it
would work better since we can't have two copies of Amanda
running the same
changer at the same time, so backup speed wise, it's probably
the same. I
am not sure if multiple copies of amanda can run the same
time, someone
please correct me if I'm wrong.

Thank you to those that wrote back yesterday, especially
Don. I used the
non-compressed device (in this case, /dev/rmt/1n), and
amanda did indeed
write filesystems until it hit EOT and rewrote that
specific interrupted
filesystem to the next tape.
Does anyone here have a changer working with more than one
drive? The
30-slot StorEdge changer I'm working with has two drives
installed, and
I'm wondering how I can best utilize both of them.
