Almost. If you want Bacula to truly ignore File and Job retention
times, I think you need to add "AutoPrune=no" to the client definitions.

Yeah, that looks about right.

That's the kind of explanation I was looking for. Now I understand why
my Volume Retention period was never being 'working' in my big Volume.

Now I'd like to be able to store (and so be able to restore from)
backups of last 90 days; Older backups must be simply erased, so to
achieve this ... would I need something like these?
Client {
...
...
File Retention = 90 days
Job Retention = 90 days
}
Pool {
...
...
Label Format = Vol-
Volume Use Duration = 10 days
Volume Retention = 90 days
}
Am I right? And the above will be equivalent to omit File and Job
Retention directives but preserving Volume Retention at 90 days?
With this Pool configuration Bacula would create about 9 Volumes (from
Vol-0001 to Vol-0009, one each ten days) within 90 days. Am I right?
So if what I believe is true then Bacula will create a tenth Volume
(Vol-0010) and just after this being marked as Used (past 10 days
more) Bacula would choose Vol-0001 to mark it as Purged and overwrite
it (Recycle), Am I right too?
So according to this Volume strategy management, Bacula will NEVER
create an eleventh Volume (Vol-0011) because would keep recycling
Vol-0002, Vol-0003, ..., Vol-00010 (and then Vol-0001 again). Am I
right?
I think I'm so close to understand better Bacula Volume Management.
Thanks a lot

If you did not set any condition to limit the disk volume size or
usage the volume will grow till it exhausts your storage then the
volume retention period of 15 days kicks in.
See the first part of the following link:
http://www.bacula.org/en/dev-manual/Automatic_Volume_Recycling.html
You need to set one or more of the following:
* Use Volume Once = yes
* Volume Use Duration = ttt
* Maximum Volume Jobs = nnn
* Maximum Volume Bytes = mmm
