Methods,Apparatus,Devices and Media for Incremental Replication Based on Massive Data
With digital economy becoming the engine of high-quality development of the global economy,the whole society is entering into the era of"digitization",and the amount of enterprise data is growing exponentially.According to Gartner's estimation,by 2025,the global data scale will exceed 175 ZB.Data presents a huge quantity,variety,single storage,etc.,to realize the data storage,replication and backup between multiple clusters of big data has become a very important part of data processing and protection.In some other scenarios,due to system update or remodeling,it is inevitable to need to copy data from the original big data cluster to the new big data cluster.Therefore,how to realize efficient incremental replication of massive data and guarantee data consistency under limited bandwidth becomes a problem that needs to be focused on and solved.
