PROBLEM TO BE SOLVED: To quickly restore the redundancy of data.SOLUTION: A computer 2 includes storing means 2c and copying means 2d. Upon reception of the same data as data that has been held in a failed first device from a second device, the storing means 2c stores the received data into a first database (DB 2a) having a data structure in which data is read in a random access manner and is written in a sequential access manner. The copying means 2d copies the data stored in the DB 2a to a second database (DB 2b) having a data structure in which data is written in a random access manner and is read in a sequential access manner.
