A host computer (10a) stores data to be written in a removable medium (RM) at a predetermined timing. The host computer (10a) creates data to be transmitted from the data stored in the removable medium (RM) at a predetermined timing, and transmits the created data to a management server (20) via a network (N). The management server (20) stores the data transmitted from the host computer (10a) as backup data for the host computer (10a) that is a transmission source. Even if an abnormality occurs in the network (N), by mounting the removable medium (RM) in which the backup data is stored, the data can be backed up and restored. |
