1. A data storage method of a portable terminal, the method comprising:

  • detecting, by a control unit, an execution of an application operable to save data;

    in response to the execution of the application, determining, by the control unit, whether a residual storage space of a data storage region of the portable terminal is equal to or less than a predetermined threshold value;

    establishing, when the residual storage space is equal to or less than the predetermined threshold value, a connection with a predetermined synchronization service server through a radio communication unit under the control of the control unit;

    increasing the residual storage space to be greater than the predetermined threshold value by at least one of deleting synchronization-complete data among synchronization-enabled data stored in the portable terminal and transferring synchronization-incomplete data to the predetermined synchronization service server under the control of the control unit after a completion of the establishing the connection with a predetermined synchronization service;

    detecting, by the control unit, a save command for storing new data generated through the executed application after increasing the residual storage space; and

    storing, in response to the detected save command, the new data in the increased residual storage space of the portable terminal,wherein the predetermined threshold value is set to a value depending on a size of the new data generated by the executed application.
