A backup file can be password-protected. By default, there is no password protection for backups.
To protect the backup:
The 128-bit encryption key is sufficient for most applications. The longer the key, the more secure your data. However, the 192 and 256-bit long keys significantly slow down the backup process.
If you want to use AES encryption, choose one of the following keys:
If you do not want to encrypt the backup and only want to protect a backup with a password, select None.
Having specified the backup protection settings, click OK.
Note that you cannot change the password of a password-protected backup after the backup was created.
If you try to recover data from a password-protected backup, the program will ask for the password in a special window, allowing access only to authorized users.
