CROSS-DATA-CENTER DATA SYNCHRONIZATION METHOD

摘要

The present invention provides a cross-data-center data synchronization method. An implementation process of the method comprises: implementing writing-in of data and recording of a log; performing synchronous scheduling and pushing; playing back the log to implement the data synchronization; and performing cross-data-center data access to implement a synchronous operation of asynchronous data. Compared with the prior art, the cross-data-center data synchronization method can implement a cross-data-center synchronous operation of asynchronous data, and can improve security of the data; the method can effectively use IO resources in data centers and network resources among the data centers, and the method has high practicality and is easy to popularize.
