Thanx Arno, I'll consider commenting out the MaxVolJobs and using the

If I use a VolUseDuration = 24h , I should have each volume being marked

week-day. Is it correct?
I'd think so. But probably you better make the time less than than 24
hours, just to make sure that, in case a job starts late, the tape isn't
valid the next day.
Then comes up a possible problem about my config.
What should I do on vacation? This customer does not have a library LTO.
As a general idea, I should let them have a "vacation" volume (one tape
only) to be left inside
the LTO when they need for automatic backup every day with no human
intervention.
As I have one pool per day (I know you don't usually do like this, but
let's just discuss),
:-)
I wouldn't want to talk you out of anything, it's just that I try to
avoid problems...
is there some
way to label a volume and have it available on all pools?
No way. Each volume is always part of exactly one pool.
This way, I could reuse my pool configuration, by adding the "vacation"
volume as a valid volume
for all the daily pools, and so be reused everyday by Bacula when inserted.
If this is possible, I think I should lower the VolUseDuration of this
volume to maybe 12h, so that
it will be reused every day.
If this is not possible, what is another possibility?
Well, let the customer pay :-)
Either they hire an operator, they educate their own people, or they pay
you enough to hire someone etc.
Or, better, you set up a temporary schedule with only one tape which is
only used during your vacation. Or whatever. Perhaps I should offer my
services to your customer :-)

Hmm, I have the impression I answered these questions already...
anyway,
once again :-)
Bacula only considers recycling and purging and whatever when it looks
for a new volume. In your setting, it _has_ an existing and appendable
volume, so there's no need to prune it.
You can use Admin Jobs to call external scripts that could mark a
volume
as Used, and that could trigger pruning.
The, in my opinion, better solution is to set the Volume Use Duration
and not the Maximum Volume Jobs. You described why.
