    • A distributed system (1) includes: a plurality of nodes (100) each having a memory (102), running distributed processes, and checkpointing to create checkpoint data for each process; a node selection unit (206) which selects spare nodes for future failure recovery for each process; an allocation unit (208) which allocates the checkpoint data to the spare nodes and to be transmitted to the spare nodes to make the spare nodes store the checkpoint data in the memories, respectively, before failure occurs; and a recovery unit (212) which selects one checkpoint data for recovery when at least one checkpoint data is suitable for recovery, to activate the selected checkpoint data to run a process on the spare node, or partitions the existing checkpoint data stored in the memory (102), when any one checkpoint data is not suitable for recovery, the partitions of the checkpoint data as a whole being integrated into a complete checkpoint data; and transmits the partitions respectively from the spare nodes to a new node, and to reorganize the transmitted partitions into a complete data to be activated to run a process on the new node.
    • 分布式系统(1)包括:多个节点(100),每个节点具有存储器(102),运行分布式处理和检查点以创建每个进程的检查点数据; 节点选择单元(206),其选择用于每个进程的将来故障恢复的备用节点; 分配单元(208),其向所述备用节点分配所述检查点数据并将其发送到所述备用节点,以使所述备用节点在故障发生之前分别将所述检查点数据存储在所述存储器中; 以及恢复单元(212),当至少一个检查点数据适合于恢复时,选择一个检查点数据进行恢复,以激活所选择的检查点数据以在备用节点上运行进程,或者分割存储在存储器中的现有检查点数据 (102),当任何一个检查点数据不适于恢复时,整个检查点数据的分区被整合到完整的检查点数据中; 并将分区从备用节点分别发送到新节点,并将所发送的分区重组为要激活的完整数据,以在新节点上运行进程。
