If you are giving users ability to create automated backups, I’m suggesting that it would be desirable to have the option to have the destination NAS mirror the source.
As it stands now, the destination never deletes any files or folders. It only adds to an ever growing list of files and folders.
Ideally, the user should have the OPTION to allow the remote backup job the permission to delete files and folders that are no longer on the source. Some users may want to preserve these files, but in our case, we would like to have an exact copy of the current source.
