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 borg with borgmatic. Heck, if you’re using Nextcloud AIO, borg is built in. It uses rsync, and takes incremental, deduplicated backups. I like it because it’s mostly just setting up ssh and a config file.
More specifically I use Nextcloud’s built in borg and these two containers:
Borgmatic
Borgserver
Edit: I forgot that for my personal devices I use PikaBackup, which also uses Borg.
Vorta is an awesome front end to Borg for machines with a gui.
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
