Abstract
An apparatus and method that stores a status of a system immediately before an interruption of a power supply. A request for a status-storing process is outputted from an application to a check point manager in a module. A request for an execution of a snapshot output to components such as the application and a device driver is outputted to the manager. A sequence at this time is based on a sequence recorded in a status-storing database and represents a dependence relation between the components. When each component receives the request for the snapshot output, a function existing in a particular address for each component is read and the component status is outputted as a snapshot file through the manager to a non-volatile memory.
