I would like to use a cloud backup service on my home server. I am a complete beginner. I purchased a subscription for Proton Drive, but it looks like that just won’t work. Is there a secure cloud backup that works well on Linux? Bonus points if there’s a way to use proton drive. Extra bonus points, if I can set it up for automatic backups through a GUI.
Maybe consider a Hetzner storage box. They support borg, restic, rsync and probably more, there’s no ingress or egress fees and you get unlimited traffic. Very nice for off-site backups if, like myself, you’re on a limited budget.
