If you spin up a digital ocean droplet for $4/mo, then enable droplet backups for $1/mo, you'd be able to use rsync proper. Any hosting service would serve this task, but follow hardening guides and move ssh off of port 22. It looks like rsync.net would be cheaper, though, and have the benefit of zfs scrubbing.
