Your BitBox02 hardware wallet automatically creates a backup during setup, storing it on a microSD card. This backup encapsulates your wallet's seed, enabling you to recover your entire wallet, including all future transactions, without the need for additional backups.
Is it necessary to update your backup after each transaction?
No, updating your backup after each transaction is unnecessary. The initial backup contains your wallet's seed, which deterministically generates all your cryptocurrency addresses and private keys. This means that all transactions, past and future, are inherently recoverable from this single backup.
Ensuring the security of your backup
To maintain the integrity of your backup:
- Secure storage: Keep your microSD card backup in a safe, secure location, protected from physical damage and unauthorized access.
- Optional recovery words: For added redundancy, you can display your wallet backup as 24 recovery words and write them down.
By following these practices, you ensure that your backup remains a reliable tool for wallet recovery, safeguarding your assets effectively.
