Hi Marc,

Yes. This is for preserving your data as long as possible. In your pool definition, you have configured:

Maximum Volume Bytes = 50G # Limit Volume size to something reasonable
Maximum Volumes = 100 # Limit number of Volumes in Pool

This way, Bacula will only recycle a volume if the limit of 100 volumes is reached and also if it could not find an appendable volume available in the pool. You have less then 50 volumes up to now.

Best regards,
Ana

Hi Ana,

Does this mean that Bacula prefers to create new volumes over recycling old ones?

Here's the output, Vol-0001 for example isn't used  by any backup jobs looking at the bacula database, as are 15 others:

Hello Marc,

Could you post a "list media" output? Bacula will just recycle a volume when there is no one available for append and it is not possible to create a new one (and you have automatic labeling configured).

Best regards,
Ana
