An innovative mechanism of a file-backup system concept is discussed. In the proposed file backup mechanism, the combination of the following technologies such as a spatial random scrambling of file data, a subsequent random fragmentation of the file, the corresponding encryption and duplication for each fragmented one by using a stream cipher in each encryption stage, and the corresponding notification of the history data of the used encryption key code sequence which we call metadata in addition can effectively realize the highly secure and prompt file backup system economically only when they are combined at the same time. In case of disaster occurrences in data backup center, the prompt data recovery can be easily and securely achieved by making use of a widely distributed great amount of PCs or cellular phones via several supervisory servers which are secretly diversified and functionally combined mutually. This paper proposes the above mentioned state-of-the art hybrid disaster recovery mechanism and its basic characteristics.
