HA redundancy options (self.homeassistant)

I'm currently running HA on a Pi3... it works fine, but it's now a single point of failure.

I have some new hardware arriving to run VMs in and was intending to move HA to it, but now I'm wondering if I can have HA in 2 places for fault tolerance.

I'm aware that there's no built-in failover options, but has anyone done something similar?

HA might be possible in a active passive configuration if you don't have any dependencies on external hardware like a zigbee stick. Active active would need support by HA and I don't think that is implemented.

I think the most secure thing is to keep regular backups so you can roll back easily.

Thanks, yes, I think active-active would be another magnitude harder... and would need database, history, etc on shared storage... over the top to jist ensure the lights stay on.

And backups are essential for all use cases (and not just the built-in HA backup left on the device / VM / container that just failed!)

Thanks
