I would like to add some information here. Instead of deleting these volumes, if you have your pool configured for recycling, you can have your pools configured with the "Action On Purge =
truncate" option. This way, when you purge a volume, Bacula will truncate it and avoid wasting of disk space.

If you delete these volumes from Catalog, yes, this will work. But if you just purge or prune your volumes, they will still exist in your Catalog. So for deleting the purged volumes the script
should check if the VolStatus equals Purged.

So it is possible to write a script that will search the database, using the volume names (filenames)
and if it is not found, I can delete the volume.
The reason I’m asking is I had a very large backup job get cancelled because it ran overtime. I’ve
since extended the run rime but I still have the cancelled job with a couple of hundred volumes and I would like to reclaim the diskspace.

Just to clarify for myself,
As I understand it, if I purge a job, that means it will remove all reference to the job and the files in the job from the database and mark all the volumes used for that job as purged.
If that is correct then:
1. If I'm using disk based backups, the files will still be there. Correct?
Correct. Your volumes are not marked purged and all your data will still be there.
2. When the job runs again, it will re-use those volumes/filenames, overwriting them. Correct?
When the job runs again, the recycling algorithm will be performed by Bacula. If you have recycling correctly configured Bacula
will re-use volumes. Doing purge in jobs or files do not purge your volumes. So this will not let your volumes available for recycling. You need to purge volumes and configure them for recycling in your confs.
3. Will it do that before creating new files?
Bacula will just recycle a volume if it cannot create a new volume when automatic label is configured. If you want Bacula recycles
your volumes, then you should limit the volumes in the pool. This way, when it is not possible for Bacula create new volumes, then the volumes already in the pool will be recycled.
4. Is this also true of a job that was cancelled?
When a job starts, Bacula reserves a volume and will begin writing to the volume. For canceled jobs, you will need to purge or delete
them. But this will not delete or purge the volumes associated with it. Mainly because the volume could have been used by other jobs before and there will be data on it.
