Data updating system and method

A data updating system applicable to a at least a first server and a second server linked by a network system for establishing a network connection, wherein each of the servers is determined to be in a normal or an abnormal operation condition according to heart beats transmitted between the servers, the data updating system comprising at least:

• a storage for storing updated data;
• at least a receiving module provided in the first server for receiving an request for data updating and updated data;
• a processing module for storing in the storage the updated data received by the receiving module at the time the receiving module receives the request for data updating, and for refraining the first server from transmitting the heart beat to the second server, so that service operations provided by the first server are taken over by the second server linked via the network system, in order to the updated data stored in the storage to be installed in the server;
• and
• a reboot processing module for rebooting the first server so as to resume the service operations based on the updated data received, upon detecting completion of the installation of the updated data in the first server.
