Hi all,

I'm looking at migrating my existing TSM5.5 backup solution to Bacula. 
I'm hoping some people could point me in the right direction.

I currently have TSM set up with a 40Gb disk volume on the local server, 
which is then migrated to a group of eSATA drives. On the eSATA drives I 
have volumes (usually 300-400Gb in size) that I VARY ONLINE via a udev 
script when I plug the drive in.

The idea is that the 40Gb on the local disk acts as a buffer which is 
once a week migrated to the volumes on the eSATA drives:

ie:
tsm: SERVER1>q vol
Session established with server SERVER1: Linux/x86_64
   Server Version 5, Release 5, Level 7.0
   Server date/time: 08/02/13   12:31:09  Last access: 08/02/13   12:01:01


Volume Name                  Storage         Device         Estimated 
     Pct      Volume
                              Pool Name       Class Name      Capacity 
     Util      Status

I'm trying to figure out how to replicate this in Bacula - however I 
haven't had much success at this stage. I did find some documents that 
are nearly 4 years old in relation to using removable media - but a lot 
changes in 4 years!

Does anyone do something like this already? How can I handle the eSATA 
drives? Is there a better way?
