Abstract
An information processing system has: information processing apparatus installed at each site, the apparatuses being interconnected with each other; fail-over processor realized by program executed by a processing apparatus, wherein when failure occurs, the fail-over processor performs to fail-over of making another different from the processing apparatus hit by the failure inherit processes executed by the processing apparatus hit by the failure; a recovery capability judge for judging whether essential data is managed in recoverable state at any processing apparatus excepting the processing apparatus hit by the failure, when the fail-over is executed passing from the processing apparatus hit by the failure to the other, the essential data necessary for performing fail-over; and backup data generator for generating backup data necessary for recovering the essential data if the data is not managed in recoverable state.
