Abstract
A second computer transmits, to a first computer, confirmation data including identification information and a version number of copy data updated in a cache. Based on the confirmation data received from the second computer and information stored in the persistent storage device, the first computer extracts the identification information and the version number corresponding to the copy data to be written to the persistent storage device, from the confirmation data, and transmits response data including the extracted identification information and the version number to the second computer. Based on the response data received from the first computer and information stored in the cache, the second computer determines the copy data in the cache to be transmitted to the first computer so as to be written to the persistent storage device.
