Wouldn't it still be more efficient to let AMANDA's planner take care of
which backups go to which drives and at what times?

Thanks.

That's not exactly true.  I use both drives in my changer simply by running
two configs simultaneously.  To some extent, it's just an added level of
parallelization.  When I had only one drive and was using 'runtapes=2', the
backups sometimes ran well into the day.  With two drives, two configs, and
runtapes=1, they're always done in the early AM.

As to the original question, I've got ~4.8TB of used space over 4 servers
(out of ~5.2GB formatted space), and back it up using a 2 drive, 19 slot
AIT3 changer.  With a new 6TB server arriving Monday, I'm looking hard at
LTO3 changers...
