6. Click Next.
If you chose the Advanced option in Step 1, the Encryption page appears.
18. Optionally, on the Encryption page, to enable encryption, select Enable Encryption.
Encryption key fields appear on the Encryption page.
NOTE: If you enable encryption, it will be applied to data for all protected volumes for this agent
machine.
You can change the settings later from the Configuration tab in the Rapid Recovery Core Console.
For more information about encryption, see the topic Understanding encryption keys .
CAUTION: Rapid Recovery uses AES 256-bit encryption in the Cipher Block Chaining (CBC) mode
with 256-bit keys. While using encryption is optional, Dell highly recommends that you establish an
encryption key, and that you protect the passphrase you define. Store the passphrase in a secure
location as it is critical for data recovery. Without a passphrase, data recovery is not possible.
19. If you want to encrypt these protected machines using an encryption key that is already defined on this
Rapid Recovery Core, select Encrypt data using an existing Encryption key, and select the appropriate key
from the drop-down menu.
Proceed to
Step 21 .
20. If you want to add a new encryption key to the Core and apply that key to these protected machines, then
enter the information as described in the following table.
