Do you have a local friend who would like to swap backup services with you? Each of you buys and configures a Raspberry Pi with a 2TB disk. Encrypt a storage filesystem. Load up your first backup, then swap boxes. Now you each have remote rsync/rsnapshot/rclone/ZFS/whatever targets, and if you run into big trouble, you can go get the box back for a really fast restore.
