The data storage methods used in high-availability systems can be divided into ordered storage and unordered storage. The storage methods are relatively simple, and there are problems of waste of storage resources and low data synchronization efficiency. In order to solve these problems, it is necessary to seek a balance between efficiency and resources. This paper proposes a hybrid storage scheme (ordered storage + unordered storage). When the server is in different states, different storage methods are selected to achieve the effect of only synchronizing incremental ordered data when the server is in steady state switching, and then realize fast data synchronization under the premise of reducing data storage space.
