Bacula version 1.37 (to be released as 1.38.0) supports multiple drives.
However, just a couple of days ago, I realized it is not going to support
what you want, which is the ability to switch drives during a backup. This is
just too complicated. This is a pity, but there is simply no way to do it
correctly at the current time.
An alternative to Arno's proposal is to use one of the two scripts in the
examples directory of the CVS source code.
The first is ak-mtx-changer.txt, which creates a virtual autochanger out of a
single tape drive. I'm not sure this script really does what you want.
The second script is in examples/multiple-drive-changer.txt. This script is
very interesting, because it uses multiple drives as if it is a single drive
autochanger with each drive being a slot. It seems to me that this script
does exactly what you want -- that is, if a tape is loaded in each of your
two drives, and you set this script up properly, it should automatically
switch between the two drives, while Bacula thinks it is a single drive
autochanger with two slots. Very cleaver of the author (Mario Wolff).
You can find it either in the CVS or in the bacula-devel archives 15 Feb 05.
