System and method for big data remote disaster recovery backup of ground application

Abstract

The invention discloses a system and method for big data remote disaster recovery backup of ground application. In the system, a service application server deployed on a data production central terminal is used for operating service application under the normal circumstances; a service application server deployed on a disaster recovery backup central terminal is used for taking over and operating core services of the data production center when disasters occur; a disaster recovery backup management application server is used for switching the core services of the data production center into a disaster recovery backup center when the disasters occur and switching the core services back to the data production center after disaster recovery; a storage system deployed on the data production central terminal is used for storing all produced data; a storage system deployed on the disaster recovery backup central terminal is used for storing all data needing the disaster recovery backup and data newly received and processed by the disaster recovery backup center after service switching when the disasters occur; a continuous data protection application device is used for sending data written in an area to be protected to the opposite-terminal storage systems in real time to achieve continuous data backup protection.

Description

technical field [0001] The invention belongs to the field of disaster recovery and backup, and in particular relates to a disaster recovery and backup system and method which are suitable for ground application systems and logically separate business disaster recovery and data disaster recovery. Background technique [0002] At present, with the increasingly widespread application of electronic computer technology and network communication technology, and the increasing variety of business types in different fields, it is becoming more and more important to research and establish systems and methods for remote disaster recovery and backup of data centers, which can provide users with The business system provides risk prevention mechanisms and disaster recovery measures to improve business continuity on the basis of ensuring data security, reduce operational risks, and reduce business losses to an acceptable level, thereby improving the service quality and level of the data ce...

AI Technical Summary

Problems solved by technology

[0003] Existing systems and methods for data center disaster recovery and backup are not suitable for application in ground application systems in some respects, mainly in the following aspects: 1) Ground application systems receive data and monitor payload operation. 1. In the entire application process from data processing to data archiving, there are many links, complex algorithms, and huge amount of calculation. If the disaster recovery center is equipped with the same business functions as the data center and achieves the same computing and processing capabilities as the data center, the cost will be too high. ; 2) The lunar exploration data received, processed and stored by the ground application system is unstructured, and a single data file is relatively large. The traditional disaster recovery system suitable for transactional real-time processing of structured data is not suitable for the business application of the ground application system , it is very difficult and expensive to ensure the real-time uninterrupted operation of the business system after disaster recovery occurs; 3) Under the premise of ensuring the uninterrupted operation of the business, the ground application system needs not only data redundancy backup in the traditional sense, but A continuous data protection scheme
