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
