To provide an information resource management program, a method and an apparatus capable of easily restoring information resources in a server apparatus by collecting the information resources remaining in the clients even when the server apparatus gets troubled.
An information resource management program causes a server apparatus to manage information resources and generations thereof which are rendered to the clients for use. When the server apparatus determines the present number of failures of the server apparatus and stores the information resources in the server apparatus, the server apparatus stores the present number of failures, the generation and generation information before the failure while associating them with the information resources and provides the information resources and the number of failures relevant to the information resources, the generation and the generation information before the failure to the clients. The generation, the number of failures and the generation information before the failure provided to the clients are used at least for restoring the server apparatus from the failure. The generation information before the failure is original information resources used as the base for updating the information resources, which include the number of failures of the original information resources smaller than that of the information resources and a generation of the original information resources.
