Abstract
In a case where data synchronization between a server and a client is performed by difference synchronization, when the data of the server is restored by backup data, a mismatch occurs between the data held in the client and the data held in the server. If the previous synchronization with the client has been performed before restoring, the client is synchronized with all the data held in the server. If the previous synchronization with the client is after restoring, the server notifies the client of data update contents in the server since the previous update with the client and causes the client to update the held data.
