This is perhaps for a narrower audience, but if you run a consumer version of Windows (not Server), you can get Backblaze unlimited storage for $70/year per device.
They support encryption with a key you provide in the client, which is super convenient. Restoring individual files is pretty straightforward, but an entire drive was a bit of work last time I had to do it. For the price, it’s a nice piece peace of mind for 10TB+ of versioned storage.
