A synchronization method of a cloud service system comprises the steps of: enabling a device, when data is changed, to upload changed data to a server, and enabling the server to process the uploaded changed data and store the processed data along with a change time; and enabling the device to transmit a synchronization request signal including a most recent server connection time at a predetermined time, download log data for changed data between the most recent server connection time and current time, perform synchronization based on the downloaded log data, and update the most recent server connection time.
