Excellent - someone else who's worked this out before me! :)

Sure, that sounds good. I'll have to work out how to get Debian to automount 
the drives, but I don't think that will be beyond me. (Famous last words!)

Excellent, I'll have a browse through the manual and see if I can work out how 
to do that. Quick question - do you perform full backups every time, or just 
incrementals? I was planning on full backups once a week and incrementals / 
differentials during the week. But I'm worried about having the same drive out 
and in use all week incase of theft / fire. Is Bacula able to cope with just
swapping the drives about, i.e. performing a differential backup when the full 
backup is on a different drive?

Excellent, that makes me feel more confident!

Thanks for your advice,

Tony
