Abstract
Authenticating a backup image stored on a storage device prior to restoring the backup image. A value such as a hash value is generated based on the image to be preserved. The value is stored on the storage device in a first area accessible for writing only when the computing device is in an update mode. The first area becomes read-only when the computing device is in an operating system mode. The image is stored on the storage device in a second area accessible for writing when the computing device is in the update mode or the operating system mode. When attempting to restore the image from the second area, the value from the first area is compared to another value generated at the time of the restoration for validation.
