Patent ID: 7065539

Claim:
An information processing system for executing a plurality of works each thereof consisting of at least one job, comprising: a plurality of work servers each thereof executing at least one work on a job basis; a management server coupled with the plurality of work servers via a first network, for managing execution of the plurality of works, full backup operation and restore operation of works according to an order of a predetermined time schedule of works listed in a schedule file, the management server having a management storage device storing, in addition to the schedule file, a history file listing names of works being executed with execution start times thereof, or having been executed with execution start times and end times thereof; a plurality of file storage devices coupled with the plurality of work servers via a second network, for storing job files for the jobs constituting the works; and a backup storage device coupled with the work servers and the file storage devices via the second network, for executing full backup operation of works on a job file basis, with each of the job files storing data of a corresponding job, wherein, when a failure occurs in a file storage device after completion of full backup operation of works, the management server searches the schedule file and the history file to identify names of works being executed or having been executed after the full backup operation, as well as names of associated work servers and names of jobs of the identified works, the management server collects, from the work severs, information concerning names of job files of the identified works and names of file storage devices storing the job files of the identified works to create a fault remedy file indicating names of job files to be restored, based on the collected information, with the job files to be restored being job files of works existing between a work during execution of which the failure occurred and a work to be executed first after the failure occurred, and the fault remedy file excluding a work whose job files are all stored in file storage devices other than the failed file storage device, the management server enables a work server to execute restore operation of data from the backup storage on a job file basis, according to the fault remedy file, and after the restore operation is completed, the management server enables work servers to restart the works listed in the remedy file.
