Abstract

The present invention discloses a dual-living system data management method. A first system of the dual living system performs the data write operation directly upon receiving the data write operationrequest, the second system receives the write request rather than performing this operation directly, but forwards to the first system to execute, while the second system only does the real-time backup, so that even when the first system and the second system simultaneously receive a write operation request to the same location, the first system performs the write operation, and accordingly thereis only one write operation result at the same location, thereby avoiding the problem of data inconsistency between the two live systems, and effectively ensuring the accuracy of data backup. The present application also provides a dual-living system data management system, a device and a computer-readable storage medium, which can also achieve the above technical effects.

Description

technical field [0001] The present invention relates to disaster recovery and backup technology, and more specifically, to a data management method, system, device and computer-readable storage medium of a dual-active system. Background technique [0002] HyperMetro is a disaster recovery backup solution for storage systems. Its implementation mode is to allow the master and slave systems to undertake the user's business at the same time, and the data in the two systems back up each other and back up in real time. That is to say, both systems can accept the user's read and write operations, and after one system processes the user's operation, the other system backs up the processing result of the system in real time. [0003] However, when the two systems receive the user's write operation at the same time, different data will be written in the same location of the two systems at the same time. After real-time backup, the location will change the data to the other's data, re...
