<P>PROBLEM TO BE SOLVED: To provide a system reducing a workload on synchronization processing of a user by reducing a synchronization processing frequency of all pieces of data stored in a PC or an online storage, and allowing the user to use high-quality data on a terminal. Ž<P>SOLUTION: In this system including a server and a client, the server receives data and device information of the client, determines a data amount storable in the client to synchronize data of the client and data of the server, converts difference data between the client and the server into a data amount not more than the determined data amount, and transmits them to the client. The client stores the data received from the server. The client or the server evaluates a relevance degree between the data and the data of the client. The server transmits the data having a high relevance degree with the data used in the client to the client based on the evaluated relevance degree. The client stores the received data.
