Disaster recovery processing method and related device

Abstract

This application discloses a disaster recovery processing method and related devices. By obtaining the remote transaction log of the main storage device in real time, when the disaster recovery process is triggered, the remote transaction log and the backup transaction log are checked to be executed. A transaction log, wherein the backup transaction log is used to indicate the transaction information of the primary storage device backed up in the backup storage device; and then perform corresponding transaction operations based on the execution transaction log. In this way, the asynchronous backup process of the data of the main storage device in the disaster recovery process is realized, and the impact of network fluctuations on the disaster recovery process is avoided, and the transaction backup process in the backup storage device can be obtained due to the verification of the remote transaction log and the backup transaction log, which can It well reflects the execution sequence of the transaction, so that the business with a large flow can also be executed normally, and the accuracy of the disaster recovery process is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a disaster recovery processing method and a related device. Background technique [0002] With the development of the Internet, information security has become more and more important. Whether it is an enterprise or an individual, the degree of dependence on information security is very high. Users use the Internet through Internet data centers, and how to avoid affecting network services due to data center failures has become a difficult problem. [0003] Generally, in order to ensure the normal use of the Internet by users, a disaster recovery system is usually set up for the data center. The disaster recovery system refers to the establishment of two or more sets of network systems with the same functions. These two or more sets of network systems will include a main network system and at least one backup network system. When the main network system is work...

Problems solved by technology

[0004] However, although the cross-city strong synchronization scheme adopted by the data layer can ensure the real-time consistency between the primary and backup data, there is a problem of delay in some remote backup scenarios; and as the number of concurrency increases, the update With the increase of SQL data, if the throughput continues to increase, the average time-consuming will continue to increase, which may affect the response delay of the upper-layer business, and cause the high-traffic business to be unavailable during the peak period, affecting the accuracy of disaster recovery processing sex
