Delete orphan backups after X days by backup job or destination
Jetbackup have the option "Delete orphan backups older than" for all backups jobs.
I think it is a good idea to have this individual value for each backup job.
For example, I may have a local backup with lots (and cheap) of available space and want to store orphaned backups for 30 days. At the same time I can have an external backup, which has a higher cost and keep orphans for only 1 day.
This setting could be individual per backup job or per destination.
