As the title says, i recently printed a nice case for my RPi3 and HDD that intend to run as an offsite backup machine.
Looking for recommendations on what backup service to run. I want to backup my Nextcloud and a "changes only" backup/cloning solution would be optimal but i have yet to find one.
I recommend Restic. It's fast, it supports snapshots and compression, written in Go so it's much quicker than most other solutions I've tested. It also supports multiple different backends for transporting and storing the files so you can use one you've already got or use the restic-server (which is pretty easy to setup).
