    摘要： A storage apparatus composed of a plurality of magnetic disk devices are provided. An encoding unit generates, after dividing original data, a plurality pieces of encoded data equal to or more than the number of division by use of a code of which redundancy is variable. A redundancy control unit varies the redundancy in the encoding unit in accordance with the importance of the original data. A distribution processing unit distributes and stores the plurality of encoded data to and in the plurality of magnetic disk devices. A decoding unit retrieves the encoded data corresponding to, at least, the division number of the original data from the magnetic disk devices so as to decode the original data.

    摘要： A backup system is comprised of a main storage for storing original data and a plurality of local storages for distributing and storing the data. An encoding unit of the main storage server generates, after dividing the original data, a plurality of encoded data that is equal to or more than the dividing number by use of a code of which redundancy is variable. A distribution processing unit distributes the plurality of encoded data to the plurality of local storages, and causes the data to be stored therein. A restoring unit retrieves the encoded data corresponding to at least the division number of the original data from the local storages, and restores the original data. A redundancy control unit varies the redundancy in the encoding unit such that, the higher the importance of the data, the larger the redundancy. Furthermore, a distribution processing unit determines the distribution number such that the higher the reliability of the local storages, the more the number.
