The invention discloses a method and device for realizing multiple backups of multiple flow groups in a high-availability cluster system. The method comprises the following steps: establishing the multiple flow groups, and generating corresponding node lists in the flow groups; respectively distributing the priority in the corresponding flow group to each node in each node list, and synchronizing priority information in the corresponding node; periodically and mutually sending the priority information among various nodes belonging to the same flow group; and comparing each node with other nodes belonging to the same flow group, setting self as a current use node in the corresponding flow group if the self priority in the corresponding flow group is the highest, and or else, setting self as a spare node in the corresponding flow group. According to the invention, one master node and multiple spare nodes can be distributed to each flow group; therefore, the resource utilization rate of each node is ensured; and furthermore, the multi-machine warm backup purpose is achieved.
