Re: [Bacula-users] Need help understanding and applying some Retention/R

Hi Mingus,

When using disk volumes with automatic volume labeling, you have to tell bacula when to stop labeling new volumes... You can do it limiting the number of volumes in the pool. Also, you can try Recycle Oldest Volume = yes. Pasted from http://www.bacula.org/en/dev-manual/main/main/Basic_Volume_Management.html:

"The Maximum Volumes record can also be used in conjunction with the Volume Retention period to limit the total number of archive Volumes (files) that Bacula will create. By setting an appropriate Volume Retention period, a Volume will be purged just before it is needed and thus Bacula can cycle through a fixed set of Volumes. Cycling through a fixed set of Volumes can also be done by setting Recycle Oldest Volume = yes or Recycle Current Volume = yes. In this case, when Bacula needs a new Volume, it will prune the specified volume."

Regards,

Ana

Dear All,
I am running Bacula Community Edition 5.2.13 on Solaris 10 x86. I am trying to understand why Bacula doesn't seem to recycle when I think it should.

I have recently moved to a configuration where each Volume contains only a single Job. I had envisioned that when the Volume Retention period was reached, the Volume would be set to Recycle and reused. Instead what I'm finding is that Bacula is taking much longer to Recycle Volumes than I think it should and is instead creating more new Volumes.

This is a relevant Pool Config

Pool {
Name = Archimedes-FS_Full
Pool Type = Backup
Storage = Archimedes_Full_Files
Recycle = Yes

AutoPrune = Yes
Volume Retention = 14d
Maximum Volume Jobs = 1
Label Format = Archimedes-FS_Full-
Next Pool = Archimedes_LTO5_Tapes
}

This is a standard Job Config using Volumes in that Pool

Job {
Name = "ar-web1_Daily_Disk"
Type = Backup
Client = ar-web1.archimedes
FileSet = "Archimedes_Solaris_FileSystems"

Schedule = "Incr_0300_Wed_Full"
Pool = Archimedes-FS_Incr
JobDefs = "DiskDefs"
Full Backup Pool = Archimedes-FS_Full
Incremental Backup Pool = Archimedes-FS_Incr

Messages = Standard
Write Bootstrap = "/mnt/backup1/archimedes/bacula/bootstrap/%n.bsr"
}

This is the Client definition

Client {

Name = ar-web1.archimedes
Address = 10.0.6.101
FDPort = 9102
Catalog = Mentora_Catalog
Password = "m7pJY91cdgeYjknTffyj3/vBd+vpRzh6briOhZV5yWWN"
AutoPrune = yes

}

As you can see, the only place where I define retention period is in the Pool. Nothing should be overriding this. Yet, here are the Volumes. I can see that the period between LastWritten is 7 days, coinciding with my Full Backup Schedule, however Bacula should not be retaining 4 weeks of these files, only 2 (14d)

Can anyone explain what is going on?
