When upgrading your Tor relay, or moving it to a different computer, be sure to keep the same identity keys (stored in "keys/ed25519_master_id_secret_key" and "keys/secret_id_key" in your DataDirectory).

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.

为了简单起见，只需复制整个 DataDirectory 即可。

你可能希望保留这些身份密钥的备份，以及桥接器的 pt_state，这样如果出现问题，你就可以恢复中继。
