I think the comments made by Steen are correct, and in principle (logically) 
what you say is correct too, but in practice, Bacula handles Maximum Volume 
Bytes rather gracefully -- it notifies all concurrent jobs of the volume 
change, whereas Volume Use Duration does not.  

Anyway, the best is to test it ...
