To protect the backed up data from unauthorized access, you can encrypt the backup with industry-standard AES (Advanced Encryption Standard) cryptographic algorithm with a 256-bit long key.
Note: You cannot set or change the backup encryption option for a pre-existing backup.
To encrypt a backup:
We recommend that you use a password longer than seven symbols and containing both letters (in upper and lower cases preferably) and numbers to make it more difficult to guess.
A password cannot be retrieved. Please memorize the password that you specify for a backup protection.
