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?
This along with borg warehouse is the GOAT setup. Many others exist of course.
Borgbase for offsite backup as well. Has been rock solid and I test download files from there every now and again with no issues. Never really did a full restore since its my 3rd line backup
