Design And Implementation Of Four-Site Disaster Recovery Solution For Commercial Banking System

In recent years, the competitive business climate has made it critical to acquire and utilize much more information in order to survive. In the financial sector, in particular, data have been the most valuable core asset. So far, most Chinese national commercial banks have completed concentration of the data of the headquarter information system. By building core data centers, they allow resource sharing, improve the efficiency of data management, and make it possible for them to strengthen the oversight of branches and control of operation risks. However, as data are concentrated, so are the risks facing corporate datacenters, which demand higher availability of the information system.How do we avoid data losses resulting from various disasters?How do we ensure the availability of business systems?How do we safeguard the resistance of core business systems to disastrous events?How do we make full use of resource redundancy and geographical separation to effectively build up a disaster redundancy system while taking into account economic feasibility?As information technology keeps advancing, businesses are demanding in terms of system availability, while data backup and disaster recovery have turned into a critical part of the construction of the corporate information infrastructure. This paper explores the construction of a remote disaster redundancy system for commercial banks through two local production centers, a local disaster redundancy backup center and a non-local remote disaster backup center, in the context of a real-world bank business system disaster redundancy project, by integrating theory with practice.The disaster recovery system is an essential component of the security subsystem of the bank computer application system. And it becomes a new challenge to improve the robustness of system operation and business continuity. This paper designed and built a reasonable, universal disaster redundancy system model that meets the actual business needs of banks, and planned the construction of a disaster redundancy system of a commercial bank covering four cities by integrating multiple independent business systems using the storage-based SRDF technology, achieving good results in practical exercise. The study of the disaster redundancy system model involved in this paper will provide guidance and reference for the construction of disaster redundancy systems for financial institutions with similar structures.
