[Bacula-users] Some questions about pools and volumes

Personal Técnico Thu, 27 Nov 2008 03:07:42 -0800

Hi!

I have configured these 2 pools for backup a server:

Pool {
        Name = Incremental
        Label Format = "Server-Incr"
        Pool Type = Backup
        Recycle = yes
        AutoPrune = yes
        Storage = BackupRAID5
        Volume Use Duration = 7 days
        Volume Retention = 7 days
        Maximum Volume Jobs = 7
        Maximum Volumes = 2
        Recycle Oldest Volume = yes
        Maximum Volume Bytes = 200GB
}

Pool {
        Name = Full
        Label Format = "Server-Full"
        Pool Type = Backup
        Recycle = yes
        AutoPrune = yes
        Storage = BackupRAID5
        Volume Use Duration = 1d
        Volume Retention = 2 months
        Maximum Volume Jobs = 1
        Maximum Volumes = 1
        Recycle Oldest Volume = yes
        Maximum Volume Bytes = 200GB
}

With this configuration, I get 2 questions with no answer:

With this configuration, I get 14 days of Incremetal backups (12 Incremental + 2 Full -no prior Incremental-) going to Incremental pool and just 1 Full backup going to Full pool. Is it correct or am I wrong?
If I change "Label Format" in Incremental Pool by new value "${Pool}", what will Bacula do at the moment of generate the second volume? If pool has variable expansion, first volume will be labeled as "Incremental" (without jobid number), but what will be the name of the second volume??
In Full pool, where I have only define 1 maximum volume, when second backup is going to execute (1 month later from first one), bacula will prune/purge volume because it was marked as "Used". Is there any way for avoiding a full prune/pruge and only delete some records (not all volume)? Maybe is "volume retention" the solution?

Thanks for all!!
