Theoretical question about umbrel-os

[lukechilds]

No, we don't restore Lightning channel state because that would be risky for the reasons you mentioned. We restore from LNDs static channel backup. This doesn't update per state change, it only updates per channel open. As long as you have a backup since the last channel you opened, the recovery process can be initiated. It's not trustless, it requires your peers to cooperate to successfully recover your funds, but there are some incentives at play to encourage them to work with you. It also results in force closing all channels to re-claim the funds on-chain.

ACINQ use a similar model and wrote a good article on it: https://medium.com/@ACINQ/adding-data-loss-protection-to-eclair-598c62494096
