Hiya,
If I remember correctly from my testing when I setup my Bacula install, Volume
Use duration is only checked at the beginning of a job. I remember this because
I was expecting the volume to 'magically' change to used exactly 23 hours after
it was first written and it wasn't changed until the next job went to run and
realised the volume had expired. (Or I triggered a check doing a status dir
from memory)
Your example sounds like you are trying to use it to force volumes to
switch/rotate in the middle of one. I dont believe what you are trying to do
will work properly anyway as the job will continue running until it finishes
under your scenario.
"Maximum Volume Bytes" on the other hand will do what you want as once a Volume
reaches that size it is marked as 'Full' (I think) and Bacula will move on to
the next job.
