A server system includes a rack, a power interface, an uninterruptible power supply (UPS), a number of first servers, and a second server. The power interface is configured to connect the server system to an input power source. The UPS is configured to provide emergency power to the server system on a condition that the input power source fails. Each first server is configured to process data when the server system is powered by the input power source and shut down properly immediately on a condition that the input power source fails. The second server is configured to back up the data in process of the first servers in real time when the server system is powered by the input power source and configured to back up its data in process and then shut down on a condition that the input power source fails.
