Heey I am a newbie to the community, so sorry if it sounds stupid,

I have set up an HA proxmox cluster with three zimaboards on my local network that run a couple of VM's in failover mode. Now, the problem is this. When my house lits fire the whole system will collapse. Or when my router or switch stops working, since I only have one switch and one router connected to the internet

Question: Is it possible to setup a system in which even if my home HA cluster brakes down, that the system starts to run on a different geographical location ?

Maybe a VM on site A as the master site that is in rsync with a VM on site B ? Then if site A drops out the DNS that points first to site A will automatically point to site B ? Then the only data loss will be the time inbetween the last sync and the system failure.

Or maybe by using a VPN connection to create a HA cluster with two nodes at site A and the third at site B ?

Another idea I thought would be to have an PBS server on site B that syncs every x minutes with site A. Then maybe a script can be written if site B fails to backup A that it will automatically spin up the VM's that it failed to backup and change the DNS to site B ?

Thank you for reading!!!
