I run HA as a container in a vm. I back HA data up nightly and the compose script for running HA is archived on github. If the vm dies there is another vm that can bring it back up. If the host dies (I have a pool of xenserver (xcp-ng) hosts, so it would be a major domestic disaster if they all croaked) I have a fallback to run HA on docker on wsl. If the house burns down all the scripts are on GitHub and the backups get sent to Azure monthly. I think I’m covered.
