If set to On, which is the default,
Windows controls the caching. This
is appropriate for Windows 10, and
for versions of Windows Server
2012 and later.
NOTE:
Setting the write caching policy
to On could result in faster performance.
If you are using Windows Server 2008
SP2 or Windows Server 2008 R2 SP2,
the recommended setting is Off.
If set to Off, Rapid Recovery
controls the caching.
If set to Sync, Windows controls the
caching as well as the synchronous
input/output.

6. Click Next.
If you chose the Advanced option in Step 1, the Encryption page appears.
14. 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 machine.
You can change the settings later from the Encryption Keys page in the Rapid Recovery Core
Console.
For more information about encryption, see the topic
.
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.
15. 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.
