I use Restic and backup to rsync.net. The only reason why I use them is because they use ZFS and have a admin/user account system that allows for immutable snapshots once everything is set up. Honestly though it doesn’t matter. The backups are encrypted outside of the PC you are using Restic on. You just need a drive or a PC with storage space and SSH access that you can access.
