 This has been more difficult than I would have thought. I have used rsnapshot the past couple of years (2020-21), but have never really been happy with it for many reasons. The main reason is that it has never worked well, the rsync is reasonably fast, but the rsnapshot takes far too long. Other problems include; difficulties in set-up, and concerns will reliability. Recently I noticed that Debian no longer includes it in its repositories as of Debian 11 due to poor maintenance.....  So I have no moved to Restic, which is described here: [[home_server:home_server_setup:other_services:back-up_server]]. This has been more difficult than I would have thought.
