Have you checked out Umbrel[1]?

You can self-host Umbrel on your own hardware[2]. I'm not sure if they allow for multiple nodes to stay in sync. If (/once) they do, it'd solve for disasters / availability as well.

I have not. It looks extremely interesting and is basically what I was thinking of.
