Tor 중계기를 업그레이드 하거나 다른 컴퓨터로 옮길 때, ( keys/ed25519_master_id_secret_key 에 저장돼있고, DataDirectory 내keys/secret_id_key 에 저장된) 신원 키를 동일하게 유지해야 하는 것이 중요해요.

If you are a bridge operator, also make sure to keep pt_state/. It contains data required for your bridge to keep working with the same bridge line.

For simplicity, just copying over the entire DataDirectory should work too.

You may wish to keep backups of these identity keys, plus pt_state for a bridge, so you can restore the relay if something goes wrong.
