Archiving job files saves the files to separate tape storage device or to disk volumes on the network. The files are saved in context and information about the job is retained in the database.
Purging job files removes archived files from the volume on which you created the job. This frees up active disk space but retains a record of the purged files so that they can be retrieved later. You can purge job files only if they are already archived.
Retrieving job files restores them back to the volume on which the job was originally created. You can retrieve job files only if they were previously archived.
Destroying is different from purging a job, where job data is retained in the database. Destroying a job completely removes the job from the system, and removes all information about the job from the database.
In Job Manager, jobs that are archived to disk or tape appear on the Storage and History tabs.
