To encrypt a backup file with a password, select the file from the Backup Job dropdown list and click the Options button. Click the Password tab and check the Protect This Backup With A Password check box. Enter and confirm your password and click OK. Be sure to choose a password that you'll remember, because there will be no way to access this password information without it. You won't need to enter your password the next time you back up this same file--you'll only need it if and when you want to restore the backup data.
