I would like also to see such feature in Bacula :-) (even if a 
workaround already exists)

Have you any idea on how Bacula would choose when it should start a new 
"backup stream" (can be automatic, by fileset configuration, etc..) ?

I think that it would be nice the spread the load between physical 
disks, and not only trying to read the same FS with many threads.

Bye
