I'm a little bit confused about Volume Use Duration and Volume Retention.
When a pool, such as the daily pool is configured with a Volume Use Duration of
4 days (let's say Monday - Thursday) the VolStatus is Append until the Thursday
backup is complete; this part is clear enough...but the Volume Retention bit
confuses me.
Lets say the same pool has a Volume Retention set to 9 days and it is called in
the WeeklyCycle schedule.
To summarize here is my puppet config (very similar to the BareOS config):
bareos::director::pool{'Daily':
type => 'Backup',
recycle => 'yes',
auto_prune => 'yes',
volume_use_duration => '4 days',
volume_retention => '9 days',
maximum_volume_bytes => '1G',
maximum_volumes => '10',
label_format => 'daily-${NumVols}'
}
bareos::director::schedule{'WeeklyCycle':
run_spec => [
['Differential', 'Pool=Daily monday-thursday', '23:30'], # 11pm (sons)
# ...
]
}
Now my question is, will the Volume be recycled on the 2nd Monday after the
first backup (on a Monday), considering that the volume retention runs out on a
Saturday, but the WeeklyCycle isn't called again until the 2nd Monday?
Thank you,
Andrew J. Leer

Shouldn’t it be 10 or 11 days, and not 9? |
