Thanks Martin, these points are essential. When a Volume has no Job Record associated, it can be purged, and it's not what you are looking for. In general, I recommend to manage retention only at one place. Bacula is very flexible, and you have probably 10 different directives to control the retention in many scenarios. For example, set Client / File Retention and Job Retention to 50 years and set the Volume Retention to what you want. I would never prune Job Records if you can, File records are nice in general, but you might end up with a very large catalog. It is possible also to disable Autopruning in different places, doing so, you control exactly when Bacula will prune records. Keep us informed, Hope it helps!
