GBM can protect backed up data from being accessed by unauthorized people using AES encryption. GBM encrypts data on-the-fly, meaning that it encrypts files as they are being copied to the backup storage device instead of first encrypting the entire data then backing it up.
From the left navigation menu in the backup wizard select Settings.
Select AES Encryption.
Type a password twice in the Password and Confirm Password text input boxes.
Click Encryption Strength.
Choose an encryption level.
Encryption applies only to the contents of backed up files. Information about an encrypted file, such as its name, date, size, and attributes, can be viewed, without a password, by anyone who has access to the backup set.
Encryption is not supported in Easy Mode
Please store the password in a safe place. If lost, the backed up data is irretrievable.
Upon selecting a backup set with encryption protection for restore, GBM will request the encryption password. The user will not be allowed to browse, view, extract or restore data unless the correct password is supplied.
