An innovative mechanism of a file-backup system concept is proposed. 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 code in each encryption stage, and the corresponding notification of the history data of the used encryption key code sequence of "encryption metadata" in addition can effectively realize the highly secure and prompt file backup system 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 huge amount of wired PCs or mobile PCs, mobile phones, and PDAs via several supervisory servers which are secretly diversified and functionally combined mutually. This paper also proposes the network architecture which can realize user-friendly service level control mechanism using RFID. The experimental evaluation of the average response time from the Web server has been estimated in terms the memory load characteristics of the data center.
