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?
Not sure about other options but Backrest has worked wonderfully for me since day 1. Basically just a GUI for Restic. My only complaints are that jobs can’t be assigned to multiple repos and you can’t edit a job’s name or repo once created. Aside from those quirks, it works fine - I have daily, weekly, monthly, and manual jobs set up across both servers and my desktop, basically just set it and forget it.
