configurations. The Stripe and Mirror RAID modes of your My Book Thunderbolt
Duo device are software configured, and the Lion backup disk encryption feature
is not compatible with software-configured RAID devices.
If you want to use your device as a backup device with Time Machine on

encryption.

encryption.
• Convert it to individual drives and use one of them with or without
backup encryption.
(See “Changing the Device Configuration” on page 13.)
