[Bacula-users] Config of bacula-dir.conf for two drive with one autochanger

[yesi <ye...@al...>]

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:
