That's exactly what's happening. See below.

I do. This is because I'm trying to enforce a specific threshold of a
single-tape-per-day policy.
I can manage volume capacity myself. I'd like to override Bacula's
default behavior of auto-picking a tape based on status/capacity/recycle
time.
I'd essentially like to "Micro-Manage" it perhaps.
I want my tapes to be written to by the scheduled jobs for their daily
assignment, by all the jobs scheduled to run at that time, and then be
marked "Used".
The trick is, if all the jobs run at the same time, don't mark the
volume "Used" or "Full" until after they've all run.
Recycling will automatically mark them "Append" after my expected
threshold (hopefully) for re-use some time during the next cycle.
I think the problem here is that Bacula doesn't consider multiple "Jobs
{}"s as defined in *-dir.conf that start at the exact same time per
their shared schedule as a single "Job" in retrospect to on-tape format.
If there was a broader name for any series of jobs on the same schedule,
say "JobSet", "Batch", or "Aggregate", the option I'm looking for would
be called:
Maximum Jobs Batch = 1
Maximum Scheduled Jobset = 1
Thoughts?
