Description

Double standby backup architecture

This disclosure relates to a backup architecture, and more particularly to a dual standby architecture.

With the evolution of the times, many organizations that provide electronic trading services (such as banks) often use off-site backup mechanisms in order to make the connection of electronic trading services uninterrupted.

The conventional remote backup mechanism is to establish servers in two different locations (ie, the main information center containing the main server and the second information center including the backup server), and multiple The computer device group (including multiple computer devices) and the automation service device are connected to two information centers through a router. Each computer group is connected to the router through a switch to form a network backup architecture.
