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?
I use restic in combination with rsync.
Two days ago, I tried to setup unbound and fucked up my Nextcloud instance on the same host.
Restic restored /opt, /etc, /home and /var and then I used rsync to divvy them all out. For some reason, restic didn’t recognize the --delete flag so, rsync it was.
Reboot, waited 3 minutes, reload, there’s my Nextcloud login screen. Database cleaned up using occ commands and I’m back.
My restic repo sits on my main NAS, and a copy of it on another system. It holds all of my host’s aforementioned directories for easy setup and restore from either bad luck or dumb ideas.
…usually dumb ideas.
