Hi,
at the moment we have a single disk volume (file). We would like to
reuse this disk volume file so it will not grow infinitely.
We have a monthly rotation schedule (this is actually the default
schedule):
# full backup on first sunday of month, differential every other
# sunday, incremental backups other days
Schedule {
Name = WeeklyCycle
Run = Full 1st sun at 23:00
Run = Differential 2nd-5th sun at 23:00
Run = Incremental mon-sat at 23:00
}
After two cycles (two months), we would like to delete old files from
the volume file. Thus we set
FileRetention = 60 days
JobRetention= 60 days
VolumeRetention = 60 days
Recycle = yes
There is no maximum file or volume size or volume use duration
configured.
My question is: will the above settings ensure that after about sixty
days, the file volume size will reach its maximum (assuming that the
size of the backed-up data remains constant)?
No it will not. The retention period begins after a volume is marked
full or used. At 60 days it will still be append. You need to limit
the # of jobs, use duration and/or size. Then after the volume is
marked Full or Used the 60 days begins counting from the last written
date.

Then volume retention in a few hours. If you set use duration to a small number # 0 you will only be able to store data on the volume for that period. I believe a use duration of 0 means infinity (although I could be wrong).

Okay, 0 means indefinitely, so that would be completely wrong. Since I want to have a backup history of sixty days, I need VolumeUseDuration to be at least 60 days. Does that mean that in this setup database pruning will be after sixty days and file pruning after 120 days?

Maybe use duration of 59 days. Then volume retention in a few hours. If you set use duration to a small number # 0 you will only be able to store data on the volume for that period. I believe a use duration of 0 means infinity (although I could be wrong). Also remember that even on disk volumes that bacula recycles an entire volume at a time. So the jobs written on the first day will be around for 60 days but the jobs written on the 59th day will be around for less than a day. John -- John M.

Re: [Bacula-users] Reusing a disk volume
Use a new volume every day, then cycle them. You won't use any more space, you're just using it differently.
