You can "copy" jobs based on various criterias. You can copy all jobs that were backed up into one specific volume, all jobs from a client, etc. There are a few options for that. Basically, you will create a copy job that will copy your backups based on specifically conditions from one pool (where you normally have your backups) to another pool (the next pool defined in the original pool resource used for your original backups).
An interesting directive for the migration/copy pool is:
PoolUncopiedJobs This selection which copies all jobs from a pool to an other pool which were not
copied before is available only for copy Jobs.
So, sure you can copy "a volume" (all the jobs that were copied in an original volume) using copy jobs.
You´re welcome!
