Problems solved by technology

However, in the existing snapshot technology, no matter ROW snapshot, COW snapshot or other snapshots have a certain impact on the IO performance of the original data volume, so the asynchronous replication disaster recovery solution based on snapshot comparison to obtain differential data needs to be sacrificed The disaster recovery function enables the IO performance of the production site data volume throughout the life cycle, which has a great impact on the production system running on the production site, especially for systems with relatively high IO performance requirements

Abstract

The embodiment of the invention discloses a production site, a disaster backup site, and a remote disaster recovery method based on a snapshot. The method comprises the following steps: the production site writes target data into the storage equipment of the production site; when the target data succeeds in being written, the production site carries out synchronous replication on the data which succeeds in being written into the storage equipment of the production site to generate disaster recovery data; the production site sets the disaster recovery data in a data message, and sends the data message to the disaster backup site in real time through a network; the production site obtains a command used for indicating to generate a data consistency point; and the production site responses to the command to set a snapshot label in a snapshot label message, and sends the snapshot label message to the disaster backup site in real time through the network. Through the above scheme, the method does not need to execute a snapshot printing operation on the premise that disaster recovery data backup is finished, so that performance losses brought by the snapshot can be avoided, and system performance in a disaster lifecycle is greatly improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of information technology, in particular to a production site, a disaster recovery site, and a snapshot-based remote disaster recovery method. Background technique [0002] Data center disaster recovery technology is a method to copy the data and application systems in the local production site to the remote disaster recovery site through the electronic network. When the local production site cannot continue to provide services due to disasters such as fires and earthquakes, the disaster recovery site It is a technology that takes over the various businesses run by the original production site and ensures that the various business services provided by the data center are not or less affected by disasters to the greatest extent. The production site and the disaster recovery site have network connections. [0003] According to different replication methods, disaster recovery can be divided int...
