Abstract: A technique to execute a backup process efficiently when an identical file is owned by multiple persons in order to decrease storage capacity and traffic volume requirements. In a backup system including a backup execution terminal, backup destination terminals, and a management server, the backup execution terminal executes a deemed backup process for deeming the file identical to the target file and owned on the backup destination terminals to be a backup duplicate of the target file, or an actual backup process for sending the target file to the management server, each of the backup destination terminals stores the backup execution terminal and the file identical to the target file in association with each other at the time of the deemed backup, and the management server stores the target file sent from the backup execution terminal at the time of the actual backup.

Abstract: A computer system for managing batch jobs is described. The computer system includes a storage unit for storing at least one job template, and an execution unit for creating or updating a job net definition following a condition defined in the at least one job template, creating or updating a job net, or executing a discovery of a job conflict using at least one attribute or relationship in a set of data including at least one predetermined attribute of an configuration item, and a relationship between the configuration item and another configuration item, the set of data being stored in a repository and updatable through a discovery for detecting information about a configuration item. The present invention further provides a method and computer program product for managing batch jobs.
