Multi-site data synchronization method, device and system

Abstract

The invention provides a multi-site data synchronization method, device and system, which can be used in the financial field or other fields. The method comprises the following steps: receiving master site application data sent by a master site interceptor in a synchronous writing mode through first message middleware, and sending the master site application data to intra-city site message middleware in the synchronous writing mode through the first message middleware; and receiving city-wide site application data sent by the city-wide site interceptor in a synchronous writing mode through second message middleware, and sending the city-wide site application data to the main site message middleware in the synchronous writing mode through the second message middleware. According to the invention, the architecture of data transmission is optimized, the problem of data synchronization efficiency of the city-wide stations is solved, the RTO of the city-wide stations is improved, and the city-wide stations can quickly take over services and improve the continuity level of the services in the scene of the failure of the main station.

Description

technical field [0001] The invention relates to the technical field of application disaster recovery, in particular to a multi-site data synchronization method, device and system. Background technique [0002] With the popularization of Internet technology, the business activities of enterprises are informatized and digitized. In order to resist the loss of enterprise business information caused by force majeure factors (such as earthquakes, tsunamis, fires, terrorist attacks, etc.), the construction of enterprise data centers often adopts the structure of two centers in two places or multiple centers in multiple places to achieve high-speed data at the site level. Available, when the production site encounters a site-level disaster, the enterprise restores customer service through the off-site site, minimizing the impact of the disaster on the enterprise's operating activities and improving the business continuity level of the enterprise. Affected by the distance between t...

AI Technical Summary

Problems solved by technology

There will be a certain delay in data synchronization. In the case of a site-level disaster, because the delayed data is not transmitted to the disaster recovery site, the remote disaster recovery site will generally lose more than ten seconds to several minutes of business data, which will affect the business. Continuity level, so a solution that can reduce data transmission delay is needed to ensure the integrity of data at remote disaster recovery sites
