Hello everybody
I have two simple questions about expiration.
I use Bacula 3.02 on a CentOS 5.3 system. My backup schedule maybe looks a bit
standard and is as follows: Full backup on the first sunday of the month.
Expiration = 1/2 year. Every other sunday a differential backup. Expiration 40
day's and for all other day's (every mon., tue., wed., th, fr. and sat.)
incremental backups with a 6 days expiration. I backup to disk.
Question one:
Everything is running smoothly if you start your first backup on the first
sunday of a month but there is a problem if you don't. Why??? Suppose my first
backup is on a monday. Then an incremental backup is scheduled but there is no
previous backup found so the systems runs a full backup but gets the level "I".
Full backup's supposed to have a rentention of 1/2 year but in this case i
loose the full backup in 6 day's. Why has the first inremental backup which
actually is a full backup "I" as backup level?
Question two:
I have in mind to use migration to save disk space.
After the full backup has run on the first sunday of the month i perform a
migrate to move the data to an LTO2 tapedrive to save diskspace. I actually do
not understand what volume expiration i should handle in the particular pool on
disk. I thought it was a good thing to set the expiration of full backups back
from 1/2 year to 5 days. In those 5 days i migrate the data from disk to a tape
pool. That tape pool has a volume retention of a 1/2 year. Why is the full
(migrated) disk backup not purged after 5 days?? It's on tape now with an
expiration of 1/2 year.
Thanks a lot for your time.
Rgds, Paul
