Re: [Bacula-users] Help Understanding Auto Pruning?

From the manual under pool resource:
The Volume Retention applied independently to the Job Retention and the File Retention periods defined in the Client resource. This means that the shorter period is the one that applies. Note, that when the Volume Retention period has been reached, and it is necessary to obtain a new volume, Bacula will prune both the Job and the File records.
The first sentence isn't really a complete sentences, so I'm not really sure what it is trying to say. However, I think the quote as a whole means that if you have a job or a client resource that you are backing up using this pool, and if more than one of these resources has a volume retention time, then bacula will use the smallest of these retention times. You didn't include your job resources, but I assume that this is where you will find the conflict in retention times. 

hope someone corrects me if I read this wrong...



Thank you for your reply.
Yes, I read the part under pool resource which led me to checking the client resources (which have a default retention period of 60 days) and changing them to 100 years. However I have just re-read the job resource section and am unable to find any references to job retention times. Did you find something there? 

I'm still lost.  Help!!!  :)

Thanks,

Drew

I would like to prune based on the volume retention I set in pool resources, not based upon client. In reading the docs, I found that auto pruning can occur based on statements in both the client and pool resources. Thus I set all of my client resources file and job retention times to 100 years, assuming this would prevent any auto pruning from occurring based upon the clients. Then I set my various pool resources volume retention times as I wished.
However I have one pool "Default" that I really don't want to prune automatically and thus I set its volume retention time to 100 years. I assume it's associated job (and thus file?) records were pruned initially because of the 60 default retention times for clients. Now I've made the changes to bacula-dir.conf and SIGHUPed the process. But after running bscan to rebuild the job and file records, it still gets pruned every night.
Can someone explain what I'm missing? Hopefully before tonight? :) The client and pool resource portions of my bacula-dir.conf file follow. 

Thanks,
