USER DATA BACKUP SYSTEM AND METHOD

摘要

PURPOSE: A user data backup system and a method thereof are provided to maintain/store one user data in a backup server and user terminals. CONSTITUTION: A determining unit(430) determines whether to download or upload user data based on user data backup time of a backup server and user data update time of a user terminal. A data processing unit(440) decodes the user data received from the backup server. If it is determined to download the user data, corresponding user data is downloaded from the backup server through control of a controller(450). The controller controls the data processing unit to decode the downloaded user data.
