<p>The present invention reduces the time required to collect and save an entire memory image, and shortens the time until a system resumes providing services. The operating system computes hashes for memory areas in units of pages, the results of which are stored in a memory hash table, the hash values in the memory hash table are initialized, a memory image is copied to an external storage device for the first time, a hash value in the memory hash table and the memory image in the external storage device are updated with respect to a change location in the system memory, a memory area where a write occurred after the last save to the external storage device is detected, a dump request is issued, and the dump request is processed.</p> |
