Yes, dar creates new archive files on each run. But you can create an
incremental backup with only the changes.
I have a script that creates a full backup ones per week, and an
incremental backup relative to the weekly full backup on other days.
I delete archives older than one month.
That's enough for my needs, but you can implement any backup scheme with
it however, with multiple levels of incremental backup.
