• Confirmed that the MPC root extended public key listed in the output above is the same as the MPC root extended public key displayed on Cobo Custody Web; otherwise, the backup will not be valid

You can continue with the backup process once the five items above are confirmed.

You’ll need to back up the following data:

• The database folder that stores the encrypted database file; the default name is secrets.db

• The password you've used to encrypt the database file during the TSS Node initialization

We recommend that you store the database folder and the password in separate devices.
