System and method for disaster recovery backup of data processing center

Abstract

The invention provides a system and a method for a disaster recovery backup of a data processing center. The system for the disaster recovery backup of the data processing center comprises a main data processing center, at least one backup data processing center and a communication accessing sub-system, and the communication accessing sub-system is used for establishing communication links between the main data processing center together with the at least backup data processing center and at least one external custom system, and managing and realizing switching between the communication links. By the aid of the system and the method for the disaster recovery backup of the data processing center, switching time can be obviously shortened, and influence to the external custom system caused by the switching process is reduced.

Description

technical field [0001] The present invention relates to a system and method for disaster recovery and backup, and more particularly, to a system and method for disaster recovery and backup of a data processing center. Background technique [0002] At present, with the increasing application of electronic computers and network communication and the increasing variety of business types in different fields, the system and method for disaster recovery and backup of data processing centers are becoming more and more important. [0003] Such as figure 1 As shown, in the existing system for data processing center disaster recovery and backup, in the initial stage, the external user system (such as the client system) only establishes a communication link with the main data processing center to perform data interaction and processing, And when due to some reasons (for example, the main data processing center breaks down) and the backup data processing center needs to take over the d...

Problems solved by technology

[0004] However, the existing systems and methods for disaster recovery and backup of data processing centers have the following problems: (1) The switch between the primary data processing center and the standby data processing center needs to be triggered manually or semi-automatically, so the process from the start of the switch to the completion of the switch (including the cooperation or response of the external user system) requires a certain amount of time, so the interaction and processing of data will be affected to a certain extent during this time period; (2) the switching of the external user system also requires a certain amount of time, and when When the main data processing center is connected to many (for example, hundreds or thousands) external user systems, the cumulative effect brought by the switching of external user systems will be very significant, so the continuity and integrity of data interaction and processing after switching (3) Due to the above two problems, from the point of view of the overall design of the system, it is necessary to avoid switching from the main data processing center to the standby data processing center as much as possible, thus requiring the main data processing High availability of the center and ease of upgrades, thereby significantly increasing the cost of the overall system
