Using a service like rsync.net (happy customer here!) gives secure and safe backups but without the ability to run services. Which also means pretty much no matter how much I mess up, I can't expose my data to the Internet at large by mistake.

I will (and do) run Internet-facing services, but I can definitely empathise with the desire not to. And I'll only do it myself if the benefit over keeping it private outweighs the risk.
