Hello, I've just started using Bacula, and I have to say that I've found
it to be great, I just have to get the hand of it :D
But anyway, here is my question, I have this on the bacula-dir.conf (for
3 different servers to backup):
#Behemot pool
Pool {
Name = BehemotPool
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle
Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 365 days # one year
Maximum Volume Jobs = 1
Recycle Oldest Volume = yes
Label Format = Behemot-
}
#Thor pool
Pool {
Name = ThorPool
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle
Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 365 days # one year
Maximum Volume Jobs = 1
Recycle Oldest Volume = yes
Label Format = Thor-
}
#W2k3 Pool
Pool {
Name = W2k3Pool
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle
Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 365 days # one year
Maximum Volume Jobs = 1
Recycle Oldest Volume = yes
Label Format = Windows2003-
}
The reason for 3 different pools, is that we will have a lot of custom
stuff for each server.
So, I've added the Maximum Volume Jobs = 1 since I want(just for testing
now) 1 actuall File Volume per job, so that I can see in an easy way how
many backups I have, and after inserting this, I'm recieving this message
on the bacula console:
20-Sep 10:14 behemot-dir: Pruning oldest volume Behemot-0001
20-Sep 10:14 behemot-dir: Pruning oldest volume Thor-0001
20-Sep 10:14 behemot-dir: Recycled volume Windows2003-0001
First of all, I don't think you run Bacula for a year already, and so
you might have missed to update the actual volume information after
you changed the retention times in the pool definitions.
The pool definitions are used as a template when creating new volumes,
they are not automatically applied to existing volumes.
So, if you want to keep your backed up data for about one year, you
should update the existing volumes accordingly... start with 'update
volume=Behemot-0001' and use the menu, for example.
I can be almost sure that I'll recieve as well a Pruning oldest volume
Windows2003-0001 (if I haven't recieved already), I'm pretty sure the
question is basic, but I'm having a hard time finding the answer
(specially because english is not my native language, so the prune
stuff get's a little weird) what does this messages means? I k20-Sep
now that the volumes were markes as used (ie. I'm recieving messages like
this:10:14 behemot-dir: Max Volume jobs exceeded. Marking Volume
Windows2003-0001 as Used.) , and this is good, since this is the way I
want it for now, but what about the prune and recycle stuff? What's
actually happening?
Pruning takes place when, while looking for available volumes, Bacula
finds volumes or jobs that are beyond their retention times.
Basically, the corresponding data is removed from the catalog, so the
volumes is known to hold no more jobs.
Recycling is the process or actually marking a volume in the catalog
to be reusable. Recycled volumes will typically be used and
overwritten (or truncated, for file volumes) immediately.
Hope this helps you,
Arno
Thanks a lot guys.
