On that, I concur with Craig. This is ugly and quickly becomes unmanageable. Or 
is there a way to tell bacula "use the next available storage device?" That 
would make it manageable again.

It would also optimize backup times in situations where the bandwidth to the SD 
is high and the bandwidth to the FD is low (for instance, backing up 
cloud-based servers to local drives).

I know, that's what I've been doing. But it is a really ugly hack: for such a 
routine operation, one really shouldn't have to write a script - let alone a 
script that has to completely bypass bacula and directly manipulate both the 
database and bacula's on-disk volumes. To me that feels as if you told users of 
Microsoft Word "to boldface a word, you have to use a hex editor and change the 
.doc file".
