PROBLEM TO BE SOLVED: To provide an information processing system capable of shortening the time required for storing checkpoint data.SOLUTION: A checkpoint management part 7 started every time of reaching the checkpoint inquires of a memory management part 6a about the use situation of a stack region storing interface information with an OS 6 of checkpoint data (sequence Seq2), acquires the use situation as a storage object list (sequence Seq3), then specifies an effective range at the present time point in the stack region, limits to the data within the specified effective range, stores all the data within the specified effective range in a file system 8 for checkpoint in the first time, and stores data of the data within the range changed between the previous checkpoint and the present checkpoint in the file system 8 for checkpoint as difference data in the second time and after that.SELECTED DRAWING: Figure 2 |
