Problems solved by technology

[0002] After InView configures the active-active environment, during the master-slave data synchronization process, the master-slave node data synchronization may fail due to network, hardware and other reasons; after the master-slave node data synchronization fails, the master-slave node data needs to be Restoring to the slave node, the existing technology usually adopts full restore, that is, all the data in the master node is updated to the slave node to realize data restoration, but this way of data restoration takes a long time and is inefficient

Abstract

The invention discloses a data recovery method and device, equipment and a storage medium. The method comprises the following steps: respectively querying each data table contained in a master node and a slave node; comparing the queried data tables in the master node with the queried data tables in the slave nodes one by one, and determining different data tables in the master node and the slave nodes based on a comparison result; and updating the corresponding data in the master node to the slave node based on the data table with the difference so as to enable the data from the master node to the slave node to be consistent. When data restoration from the master node to the slave node needs to be realized, the data tables with differences in the master node and the slave node are determined by comparing the data tables in the master node and the slave node, and then data restoration from the master node to the slave node is realized based on the data tables, so that the data of the master node is consistent with the data of the slave node. The data recovery time can be effectively shortened, and the data recovery efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a data restoration method, device, equipment and storage medium. Background technique [0002] After InView configures the active-active environment, during the master-slave data synchronization process, the master-slave node data synchronization may fail due to network, hardware and other reasons; after the master-slave node data synchronization fails, the master-slave node data needs to be Restoring to the slave node, the existing technology usually adopts full restore, that is, all the data in the master node is updated to the slave node to realize data restoration, but this way of data restoration takes a long time and is low in efficiency. Contents of the invention [0003] The object of the present invention is to provide a data restoration method, device, equipment and storage medium, which can effectively reduce the data restoration time and imp...
