A remotely managing and controlling system and a remotely managing and controlling method are provided to a user for receiving feedback information and control right of the target device through a remote connecting device. To achieve the above goal, a remote control program is proposed and installed in a controlling device, named controlling terminal, and the target device, to determine whether operation modes can be executed through the remote connecting device. The remote connecting device transmits control commands and data to the target device, and receives the feedback information and the control right of the target device. Then, the controlling terminal can control the target device according to the feedback information for increasing the efficiency of data management. Further, the system and the method can receive a location of the target device through a tracing platform, and control the target device for increasing security of data stored in the target device.
