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.

If you are using Windows Server 2008
SP2 or Windows Server 2008 R2 SP2,
the recommended setting is Off.

.
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.
Proceed to
