Problems solved by technology

At present, the common remote disaster recovery methods are divided into two types: local master backup and remote disaster backup. Most of them are local master backup. Dual-machine hot backup) cannot effectively deal with unexpected downtime caused by data or software logic failures, such as human misoperation, network virus attacks, etc. Remote disaster backup is to place the main library and backup library in different places, and through cross- IDC synchronization, the disadvantage of this method is that the delay is high and real-time backup cannot be done

Abstract

The invention provides a remote disaster recovery method for high-availability Redis, which is characterized in that a high-availability Redis instance is deployed in a data center A and is an architecture of a master N and a slave M sentry, wherein M is greater than or equal to 1, N is greater than or equal to 1; a single-node Redis instance is deployed in a data center B, a high-availability synchronous service Server and a synchronous server client are both deployed in a central control area, the synchronous service Server acquires AOFbinlog from the high-availability Redis instance, the Redis instance starts AOF backup, the synchronization service Client obtains data needing to be synchronized from the synchronization service Server and sends the data to the remote backup library instance for backup. The remote disaster recovery method of the high-availability Redis can achieve real-time synchronization with low time delay or even without time delay, guarantee high availability of uninterrupted services and support HA architecture of various Redis, and one-master multi-slave or one-master multi-slave multi-sentinel and the like, and can realize remote disaster recovery.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a high-availability Redis remote disaster recovery method. Background technique [0002] With the development of business, users have higher and higher requirements for high availability of business systems. They are no longer satisfied with disaster recovery across availability zones. Users hope that even if a system in a certain region is unavailable, it can still be used Systems in other regions continue to provide services, which is cross-region disaster recovery. At present, the common remote disaster recovery methods are divided into two types: local master backup and remote disaster backup. Most of them are local master backup. Dual-machine hot backup) cannot effectively deal with unexpected downtime caused by data or software logic failures, such as human misoperation, network virus attacks, etc. Remote disaster backup is to place the main library and...
