Lots of people have mentioned rsynx, restic, borgbackup, and others, but which would be best for backing up nextcloud, immich, and radicale? Do all of them have a method of automatically backing up every X days/weeks? Why use one over the other, what are the differences?
It’s a GUI and a bit more than that. Restic’s biggest pain point is that periodic runs have to be set up manually. Backrest does that for you.
Although I’m using resticprofile, just because it also works(and has a nice web hook support) but I also use backrest and I highly recommend it.
