Hello list!
In my current Bacula configuration, a single Client have different
Pools for it's Incremental, Differential and Full Backup. For a
specific Client, I have the following configuration:
Job {
Name = job.ptierp-teste-top
Client = client.ptierp-teste-top
JobDefs = jobdef.default
Full Backup Pool = pool.full.muitobaixo
Differential Backup Pool = pool.diff.alto
* Incremental Backup Pool = pool.inc.muitobaixo*
}
Pool {
Name = pool.inc
Pool Type = Backup
Storage = st.tpa
* Volume Use Duration = 1 day
Volume Retention = 1 day*
Scratch Pool = scratch.tpa
RecyclePool = scratch.tpa
File Retention = 1 day
Job Retention = 1 day
Cleaning Prefix = "CLN"
}
The pool config you're posting has a different name from the one defined
as incremental backup pool for your job (missing .muitobaixo). Is this a
typo or does your real config contain the same error?
I run a Incremental Backup from Monday trough Friday and, with this
Pool (using the Volume Retention option), I want to keep only 1 day of
Incremental Backup history, but I'm keeping the Differental and Full
Backup for longer periods.
How will you restore from a second, third, ..., incremental backup
without the info from the previous backups? Without the info from the
previous incremental backups it'll be quite the annoying experience if
you need to restore a file that changed between your full backup and the
last incremental backup, involving bscan ...
Will Bacula always assume the Volume Retention from the Pool being
used period to Prune files? Even if a specifically set the File
Retention and Job Retention on the Client? Even if I have different
Pool for a single Client?
Volume retention always takes precedence over File or Job retentions.
There is no use keeping data for a backup on a volume that "no longer
exists" as far as bacula knows. As often mentioned on the list: don't
use file and job retention definitions in Pool configs. They are bugged
in the current version and don't work correctly.
As far as I know pruning should happen on a per-pool basis, applying the
correct retention periods per pool. You might want to make sure the
retention periods set for your Full pool are correct though.
Kind regards
Jeremy
