Thanks for getting back with an answer. Still curious thogh, to what cloud system or platform do you back up? Restic is a solution for organizing and managing the backup process, but not for the remote storage itself.
Literally any remote storage you can imagine works. I've personally used Hetzner storage boxes and they work fine, and their price is very good (though still not as good as Backblaze Backup if you have double digit TBs like me)
