Hi,
I suppose this was meant for the list... otherwise, I'd have to charge
you a fee ;-)

It is, but...

Indeed there is.
Bacula handles all storage devices like tape drives. And a tape drive
an only access one tape at any time.

I'd suggest to set up a "virtual autochanger".
Basically, you use one set of volume files, and several storage
devices accessing this.
Bacula will automatically choose distinct volumes for use by different
devices. There are a number of mails and how-tos available in the list
archives - search for vchanger (I just notice you know that already...)
Alternatively, set up several file based storage daemons - most
commonly per client - and use these in your jobs.
This requires more configuration, but using a template you process
with sed or awk it's easy to create files to include in the main
configuration.
Hope this helps,
Arno
