Run backup/redundant node

Is there a way that I can run a second umbrel as a pure backup/redundant node? I just had my Pi crash, and am in the process of re-syncing the blockchain right now to figure out where I stand. Unfortunately all my channels are screwed since those will be closed when restoring from backup. Is there a way to setup two Pi’s so that I can have one literally just be a mirror image of the other, so if this happens again, I can just switch over to that?


Hm ok, raid systems usually are powered externally but if umbrel os won’t play that’s bad.
