Firstly, you cannot have bareos delete files without dirty tricks. It
can truncate volumes on purge as someone already pointed out.
If I were you and wanted to have fixed number of backups regardless of
any other parameters, I'd go for maximum volume jobs=1 and apropriate
retention and Maximum Volumes. Then I'd go for a separate pool for each
client.
This way you'd have a fixed number of volumes in rotation, you'd have a
separate media file for each job and with appropriate retention settings
you'd recycle oldest volume each time.
One caveat - if you happen to have a job return an error state and want
to rerun a job earlier than it's normally scheduled, you'd have more
volumes used than you planned so you'd have to manually purge the volume
containing errored job.

I understand the core philosophy of bareos and the fact that as it
predecessor bacula are meant to backup tapes. My storage however is
consisted of HDDs only and there is no need of changing tape drives. I
am reading through the documentation and I thought I got it right, but
apparently I didn't. My goal is the following: I want to have full 7
days of backups at any given time for each client that is backed up. A
job is configured like so:
[root@directorbareos ~]# cat
/etc/bareos/bareos-dir.d/job/ufo1.delta.bg.conf
Job {
Name = example.com
Type = Backup
Level = Full
Client = example.com
FileSet= LinuxAll
Messages = Standard
Storage = examplestorage
Pool = LinuxAll
Schedule = Weekly_10pm
Priority = 20
Allow Mixed Priority = yes
Reschedule On Error = yes
Reschedule Interval = 180
Reschedule Times = 2
Run Script {
Console = ".bvfs_update jobid=%i"
RunsWhen = After
RunsOnClient = No
}
}
And my volume is configured like so:
Pool {
Name = example.com
Pool Type = Backup
Recycle = yes
Auto Prune = yes
Volume Retention = 7 days
Label Format = "example.com-"
Volume Use Duration = 14d
Recycle Oldest Volume = yes
Storage = examplestorage
}
So, how can I achieve having full 7 days of backup the most efficient
way without wasting space and having the old files automatically
deleted from the volume, not just the catalog?
