I want to create a backup laptop for my baker (with Ledger).
Am I correct in that all I need to do is to register my Ledger (or a copy of it using the same seed words) on a second laptop with Tezos running and I could use that laptop immediately as a backup? That node obviously wont have the same ID as the original but imo that doesn't matter. I'd like to try this out in the near future by shutting down the original laptop between operations. Does that eliminate my risk of double baking or is there some kind of time minimum that one needs to follow between shutting down one and turning off the other?
