Hi Martin,

I wish it were that simple, unfortunately the testing I've done shows there is 
more involved than just the order. My nightly Incrementals are set for the same 
time, and they get scheduled in the order they appear in the file. Then the 
different verify jobs are scheduled at the same time, but the verifies for one 
job type get scheduled, then the verifies for the other job type. Also, the 
first gets scheduled in one order (first client to last), while the other gets 
scheduled in opposite (last client to first).

It's like Bacula scans the job list from top to bottom, then back up, and back 
down, etc, until all jobs are queued for that day.

I like your suggestion about priorities, but the way I read the instructions 
was that jobs of a lower priority would wait until all jobs of a higher 
priority finish before starting. Since we have two tape drives, and use one of 
them for our large filesets, there would be times where the first tape drive 
would sit idle for a day or two while waiting for all the higher priority jobs 
to complete.

Am I misunderstanding the way priority is implemented?

Thanks for your help!
Tom
