Hello.

I've been using bacula for a long long time, but I can't seem to understand why, in a specific installation, volumes are recycled before I think they should. The only difference from several other installation, is the use of S3 cloud plugin.

So:

_ Bacula version is 11.0.6;

_ excerpts from bacula-dir.conf:
Client {
  Name=...
  Address=...
  FDPort = 9102
  Catalog = MyCatalog
  Password="..."
  File Retention=3 months
  Job Retention=3 months
  AutoPrune = yes
}
Pool {
  Name = Full
  Pool Type = Backup
  Recycle = yes
  AutoPrune = yes
  Maximum Volume Bytes = 50G
  Maximum Volume Jobs=1
  Label Format = "Full"
  Volume Retention=3 months
  Cache retention=31 days
  Action On Purge=Truncate
}

_ from the DB:
select volumename,volretention/60/60/24 from media where volumename like 'Full%';
 volumename | ?column? ------------+----------
 Full0021   |       90
 Full0025   |       90
 Full0026   |       90
 Full0117   |       90
 Full0112   |       90
 Full0152   |       90
 Full0111   |       90
 Full0116   |       90

_ yesterday I had:
ls -lt|grep Full
drwxr----- 2 bacula bacula 512 Aug 30 22:45 Full0111
drwxr----- 2 bacula bacula 25600 Aug 8 22:45 Full0026
drwxr----- 2 bacula bacula 512 Aug 7 22:45 Full0025
drwxr----- 2 bacula bacula 21504 Aug 4 23:53 Full0116
drwxr----- 2 bacula bacula 512 Aug 4 22:33 Full0112
drwxr----- 2 bacula bacula 512 Jul 9 22:45 Full0021
drwxr----- 2 bacula bacula 25088 Jul 4 22:45 Full0152
drwxr----- 2 bacula bacula 512 Jul 3 22:45 Full0117

_ today the volumes from July were recycled:
ls -lt | grep Full
drwxr----- 2 bacula bacula 21504 Sep 1 23:55 Full0152
drwxr----- 2 bacula bacula 512 Sep 1 22:33 Full0117
drwxr----- 2 bacula bacula 512 Aug 30 22:45 Full0111
drwxr----- 2 bacula bacula 25600 Aug 8 22:45 Full0026
drwxr----- 2 bacula bacula 512 Aug 7 22:45 Full0025
drwxr----- 2 bacula bacula 21504 Aug 4 23:53 Full0116
drwxr----- 2 bacula bacula 512 Aug 4 22:33 Full0112
drwxr----- 2 bacula bacula 512 Jul 9 22:45 Full0021


Any idea why this happens?

P.S.
In the last job's mail I see:
 There are no more Jobs associated with Volume "Full0117". Marking it purged.

So it seems job retention is the problem, not volume retention.
