Post Config of bacula-dir.conf for two drive with one autochanger 
Hi,

I'm with GNU/Debian squeeze.
 bacula                               5.0.2-3

i've got two drives and one changer (Robot works with one logical library).
I defined one "autochanger" with one logical library.
I'd like to know how to define my bacula-dir.conf on the "storage" part.

Must i define two drives in the storage part or only one drive ?
which case is the good one ?

Thank you in advance for your feedback.


Here's my configs:

Post Config of bacula-dir.conf for two drive with one autochanger 
For most purposes, you use Case 1 and always refer to your changer,
since the drive will be automatically selected when running jobs and
when doing administrative tasks, you'll be prompted for a drive.

We use something like your Case 3 though because sometimes we want to do
things like force a job to use a specific drive and by having the Drives
(and not just the Library) defined in the Director's config, we can
specify that Drive on the command rather than the auto-selecting Library.
