Hello Nick, Bill, I'm here :-) Sorry for not jumping in earlier.
Nick, I will try to summarize a bit about retention values and pruning/truncation in Bacula. Pruning is about "the deletion of jobs and files from Catalog". Automatic or manual prune will not touch the data in the volumes, but only the jobs and files records in the Catalog are deleted. The easiest way is to allow Bacula to automatically prune Jobs and Files from the Catalog. It means to have "AutoPrune = Yes" in both the Client resource and in the Pool resource. 1) having "AutoPrune = Yes" in the Client resource -> at the end of each job run associated to the Client/Pool of the job, Bacula will check if the retention have passed for all the jobids associated to the Client/Pool and the jobs and files are deleted from the Catalog if the retention has passed. You will see this kind of message: | bacula-dir JobId 5104: Begin pruning Jobs older than 6 months . | | bacula-dir JobId 5104: No Jobs found to prune. | | bacula-dir JobId 5104: Begin pruning Files. | | bacula-dir JobId 5104: No Files found to prune. | | bacula-dir JobId 5104: End auto prune. | If any job/file has reached the retention based on the values defined in the Client and/or Pool resources. The values set in a Pool resource will take precedence over the values set in a Client resource. 2) having "AutoPrune = Yes" in the Pool resource -> when Bacula needs to reuse a volume for a job (if Bacula can't create a new volume because the max number of volumes in the pool is reached and there is no volume in Append, Purged or Recycle status), the recycling algorithm will try to prune jobs and files to reuse a volume. It will start searching for the oldest volume in the pool. Then, Bacula will check if this volume has no more jobs associated with it in the Catalog (it means the jobs and files have been pruned so this volume can be reused). If so, you will see messages like: 04-Nov 15:15 bacula-dir JobId 3560: There are no more Jobs associated with Volume "Vol-0038". Marking it purged. 04-Nov 15:15 bacula-dir JobId 3560: All records pruned from Volume "Vol-0038"; marking it "Purged" 04-Nov 15:15 bacula-dir JobId 3560: Recycled volume "Vol-0038" This is a job log where Bacula couldn't create a new volume for jobid=3560 and it reused Vol-0038 because the jobs associated with it had been pruned (by automatic prune after the job run) previously. Now, to force the prune of volumes that have the VolumeRetention (value defined in the Pool resource) expired, the command is: * prune volume expired yes This command is dangerous, it will delete all jobs and files associated with any volume by comparing only the "VolumeRetention" of the volume. This value is defined in the Pool resource, but it is specific for a volume and Bacula will check the value in the "volretention" field in the Media table in the Bacula database for each volume. This is why when you change the "VolumeRetention" value in the Pool resource the value of the already existing volumes is not modified and you have to run: * update volume fromallpools All Volume defaults updated from "Default" Pool record. All Volume defaults updated from "File" Pool record. All Volume defaults updated from "Scratch" Pool record. After that, the volretention values in the Catalog for the existing volumes is updated to the value defined in the Pool configuration and the "prune expired volume yes" will use the new value to compare with. Then, to truncate volumes you must have the following configuration in the Pool resource: ActionOnPurge = Truncate Please remember to reload the configuration in bconsole using the reload command after adding the above line. After that, you will be able to "truncate volumes in Purged status" using the following command: * truncate volume allpools storage=File1 Please let us know if it helps.
