Hello, how are you doing? I'm having a bit of a struggle with bacula and his 
configuration of pools.

I am running a bacula server without tapes disk so backups go directly to a 
hard drive. Because of this limitation I thought that a maximum volume bytes 
was not necessary so I commented that part in the pools file. Now, I have some 
pools than have like 1,5 TB.

The problem is that I'm partially confused on how bacula manage my 
configuration for a pool. This is the configuration for differential backups.


Pool &#123;
&nbsp; &nbsp; Name&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp;= "All_Diff"
&nbsp; &nbsp; LabelFormat&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = "All_Differential"
&nbsp; &nbsp; Pool Type&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = Backup
&nbsp; &nbsp; Recycle&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = yes
&nbsp; &nbsp; AutoPrune&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = yes
&nbsp; &nbsp; Volume Retention&nbsp; &nbsp; &nbsp;= 8 days
&nbsp; &nbsp; #Maximum Volume Bytes = 50GB
&nbsp; &nbsp; #Maximum Volumes&nbsp; &nbsp; &nbsp; = 100
&#125;

I'm not quite sure what Recycle, AutoPrune and Volumen Retention actually does. 
What I understand reading the docs is

        Volume Retention: time until the volume goes to a purge state

        AutoPrune: automatically delete the information from the catalog when 
the Volume Retention is reached.

        Recycle: reuse the volume so you don't have a lot off volumes.


What I thought is that this will mean that the volume will get erased every 8 
days so it will go to 0 and backup again but this is not working.

I need to disable Recycle and make the bacula writes a new volume every 8 days 
and delete the old ones with a script?

Thanks for your help!
