Which file is always safe to copy as a backup of an LND node's channels?

• `channel.db`, the channel database
• `channel.backup`, the static channel backup
• Neither; channels can't be backed up

A watchtower holds your encrypted justice transactions. When can it read and publish one?

• Whenever it likes, since it holds the data
• Only after your peer broadcasts a revoked state
• Only once the channel's delay has run out
