Abstract

The invention discloses a data synchronization method and device. The method comprises the steps of detecting synchronization operation, wherein the synchronization operation is used for making a request for synchronizing a target type of data of a first node to a second node; obtaining a synchronization task triggered by the synchronization operation, wherein the synchronization task is used for synchronizing the target type of data stored on slave devices of the first node to the second node, and the first node comprises a master device and a plurality of slave devices on which the data on the master device is backed up; carrying out a synchronization task, reading a target message containing the target type of data from a message queue, wherein the messages cached in the message queue carry various types of data obtained from the salve devices of the first node; and storing the target type of data in the target message to the second node. According to the method and the device, the technical problem that in related technologies, the efficiency is relatively low when data synchronization processing is carried out is solved.

Description

technical field [0001] The present invention relates to the field of the Internet, in particular to a data synchronization method and device. Background technique [0002] Data backup is the basis of disaster recovery and data analysis. It is mainly the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by system operation errors or system failures. Traditional data backup mainly uses built-in or external tape drives for cold backup. But this method can only prevent man-made failures such as operating errors, and its recovery time is also very long. With the continuous development of technology and the massive increase of data, many enterprises have begun to use network backup. Network backup is generally realized through professional data storage management software combined with corresponding hardware and storage devices. [0003] Mysql provides a multi-master and...
