Setting backup encryption options
Use this step to set backup data encryption parameters.
This step appears only when performing backup on SQL Server 2014 and is available for editing only if the Back up to a new backup media option was selected on the Backup Media Options step.
Encryption
Check this option to enable the data encryption while creating a backup.
To encrypt during backup, you must specify an encryption algorithm, and an encryptor to secure the encryption key.
Algorithm
Select one of the encryption algorithms for a backup:
AES-128
AES-192
AES-256
Triple DES
Encryptor
If you choose to encrypt you also have to specify the encryptor. Encryptors can be a master key certificate or an Extended Key Management asymmetric key from the master database. All available encryptors are listed in the combobox.
