PURPOSE:To reduce a file space for receding a data space and to reduce overhead by saving/reconstituting only data specifying backup attribution at the time of saving/reconstituting a user data space in check point restart. CONSTITUTION:A backup data control table in a load module 25 outputted by a linker 22 is referred on a check point at the time of executing restart and backup data are receded to a backup data storing file 4. At the time of reexecution, the backup data are restored from the file 4 and restarted. Since only the data specifying backup attribution are saved/reconstituted in the saving/ reconstituting data of the user data space at the time of check point restart, the file space for receding the user data space can be miniaturized and overhead based upon saving/reconstituting can be reduced. |
