1. A method for resuming data for data synchronization between a server and a client when the synchronization is abnormally terminated, the method comprising the steps of:

  • if the data synchronization is abnormally terminated while the client is transmitting data to the server, terminating a data synchronization session by the client after storing, in the client, state information of the data indicating a state thereof at a time when the data synchronization is abnormally terminated;

    notifying the server, by the client, of a resumed synchronization session when the client attempts to reperform the data synchronization after the data synchronization session was terminated;

    resuming the transmission of data from the client, beginning with a data item that was being transmitted to the server at the time of the abnormal termination, by using the state information of the data; and

    updating data previously stored in the server using the data received from the client.
