PROBLEM TO BE SOLVED: To provide a fault recovery system (100) using sequenced and cascaded re-synchronization. SOLUTION: The fault recovery system (100) has a plurality of data centers (102, 104 and 106) and a distributed control system (110). Individual data centers (102, 104 and 106) have a communication interface (102A, 104A and 106A), a data storage (102B, 104B and 106B), and a controller (102C, 104C and 106C). The distributed control system (110) can be distributed to the controllers of the plurality of data centers and implemented by the controllers. The system adjusts operations via the communication interfaces of the plurality of data centers, and re-synchronizes the plurality of communication links (L1 and L2) between a pair of data centers among the plurality of data centers. The communication link contains at least one synchronous link and at least one asynchronous link. COPYRIGHT: (C)2005,JPO&NCIPI
