Abstract
A primary system includes a first node and a second node that backs up the first node. A secondary system includes a third node and a fourth node that backs up the third node. The first node transmits data update information generated in response to a data update in the first node, to the second node and the third node. The fourth node determines a degree of progress in transactions indicated by data update information obtained through the second node and a degree of progress in transactions indicated by data update information obtained through the third node, identifies data update information indicating a further progressed transaction, and reflects the data update information in stored data of the fourth node.
