Sounds really easy but how do you backup this key to another Yubikey? Or do you simply have two, and always add two keys to each server?

You can also look into Trezor - it has much better backup system, among other advatages compared to yobikey

The latter, yes. That way it's trivial to revoke one if it gets lost.
