Backup files are one way to fully restore a wallet. For more information about how to restore a wallet, refer to other help documents.
You can go to the backup function page and click the backup button to make a backup for the current wallet immediately. If the backup is successful, the file address generated by the backup file will be displayed. The backup file is a encrypted document saved in the file system of the mobile phone.
In addition, the wallet automatically generates a backup file every 7 days by default (Note: the backup requires opening the wallet, meaning that if you do not actively open the wallet, you cannot trigger the automatic backup logic every 7 days). You can also turn this off on the backup feature page.
