The embodiment of the invention discloses a synchronizing method, a synchronizing device and a synchronizing system, relates to the field of computers, and solves the problem that in the synchronizing process of a host computer and a backup computer, the volume of synchronized data is large, which reduces the reliability and the operability of the system. The synchronizing method comprises the following specific steps: the host computer acquires an operational order, operates corresponding data of the operational order in the host computer according to the operational order, and sends the operational order to the backup computer; the backup computer receives the operational order sent by the host computer and operates corresponding data of the operational order in the backup computer according to the operational order. The synchronizing method, the synchronizing device and the synchronizing system are used for synchronizing the host computer and the backup computer.
Description
technical field [0001] The invention relates to the field of computers, in particular to a synchronization method, device and system. Background technique [0002] With the development of technology in the server field, the out-of-band management system has become an indispensable part of the entire system. In order to ensure the availability of the management system, the industry currently adopts a "1+1" backup solution for the management server . In the active-standby technology, how to ensure that the data and state of the main machine and the standby machine are consistent is a key issue, especially in the server field, the management server undertakes the function of analyzing and monitoring the status of the entire system, so The analysis needs to refer to the historical data of the system. If there is an inconsistency between the data of the main machine and the standby machine, it will lead to uncertainty in the analysis and prediction of the system status, which wi...
