Hetzner will increase their prices by April, still a good value

+1 for Hetzner Storage Boxes, even thought with the general increase in pricing for hardware I don't know how long they'll be able to keep them so cheap.

To back up the data automatically, I use BackRest (it's a nice web interface that uses restic under the hood).

Another +1 for Hetzner.

I did an initial backup of my music (so I wasn't concerned about encryption) with plain old rsync to get a feel for the system first, do a restore, etc. to feel comfortable with it all - and see if there were any hidden costs.

Then I wiped all that and moved over to rclone to encrypt my data into different chunks (photos, music, work, etc)

It all worked well and they even skipped charging me 1 month becuase I hadn't exceeded their minimum charge (rolls up to the following month)

I've had proactive emails from them notifying me of work which might have reduced my ability to access their system, but ad it was outside the time of my backups, then no issue.
