Summary:PROBLEM TO BE SOLVED: To provide a disaster recovery data communication system capable of recovering a system (data) in a short time as much as possible in case of various disasters and instantaneously taking over a business from a system in another place. SOLUTION: A transmitting-side data communication unit A and a receiving-side data communication unit B are connected in parallel through a plurality of communication lines 1, 2 and 3 differed in line system. The transmitting-side data communication unit A comprises a storage device 7 storing data; a communication control device 11 selecting a plurality of communication lines so as to distribute and transmit transmitting data among the stored data according to a distribution rule determined according to the data concerned; and a communication line switching device 12 switching the communication lines according to the communication control device. The receiving-side data communication unit B comprises a communication line switching device 12 switching a plurality of communication lines; a communication control device 11 controlling the communication line switching device to select a plurality of communication lines and integrating the data from the communication unit A; and a storage device 7 storing the data.
