Check Backup on Trezor Safe 3
The dry-run recovery is a useful way to test your recovery seed. It is recommended to test your seed before you wipe your Trezor device and before every firmware update. It allows you to double check that your recovery seed backup is correct.
By starting the verification process, you are telling the device that you want to run the recovery process, but you do not want the device to remember the seed. Instead, the device compares the seed saved in its storage and the seed you have just “recovered”. If the seeds match, a message on your Trezor device screen will tell you that your backup is okay. If they do not match, then the device screen will display an error message.
