Abstract
A data synchronization method for a host machine and a backup machine of a station application server includes the following steps: receiving initial data sent by the host machine and storing the initial data in a backup machine local file by the backup machine to realize data synchronization between the host machine and the backup machine in an initial state after establishing a communication between the host machine and the backup machine; and receiving message data sent by a station terminal device in real time and storing the message data in a host machine local file, then sending the message data to the backup machine by way of polling, and receiving the message data and storing the message data in the backup machine local file by the backup machine to realize data synchronization between the host machine and the backup machine.
