A first information processing apparatus transmits a message storing a replica of data stored in the first information processing apparatus. The message has an unspecified destination. A first relay apparatus detects a second information processing apparatus provided in a network to which the first relay apparatus belongs. The first relay apparatus selects, as a transfer destination of the message, the second information processing apparatus or a second relay apparatus upon receiving the message. The first relay apparatus transfers the message to the selected transfer destination. The second information processing apparatus stores the replica therein upon receiving the message. |
