A method is provided for supporting recovery processing from a failure of a storage device in a computer system. The computer system includes a processing unit and a storage device, and in which a batch job consisting of a plurality of jobs is executed on said processing unit. Transition history information which includes information concerned with executed jobs and information concerned with an operated on data-set is obtained during execution of a batch job. At the time of recovery processing in the event of a storage device failure, the transition history information is inspected. Jobs that have performed an output operation to a failed storage device, re-execution of which is required for recovery processing, are extracted as direct re-execution jobs. Further, jobs on which a data-set operation is effected by the direct re-execution jobs are extracted as indirect re-execution jobs. Then, a transition of the data-set operation performed in a batch job is inspected. On the basis of the results of inspection, a data-set and generation of a data-set to be restored from a backup, and the need for deletion of a data-set and a method and timing thereof are determined. Then, information that is used for supporting the recovery operation is edited by using these results and the edited information is outputted as documents. |
