How to keep your Tor relay identity when upgrading or moving it
When you upgrade or move your Tor relay to a new system, you can preserve its identity and reputation by copying its key files.
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.
برای سادگی، فقط رونوشتکردن کل پوشهٔ DataDirectory نیز باید کار کند.
شاید بخواهید از این کلیدهای هویت، بهعلاوهٔ pt_state برای یک پل، نسخهٔ پشتیبان تهیه کنید، تا در صورت بروز مشکل بتوانید رله را بازیابی نمایید.
