To Achieve Long-range Business-class Cluster Of Disaster

In recent years, the large centralized data has become a major focus of my government, enterprise information construction trends. Along with the large centralized data on the achievement of enterprise-class data center technical risk is relatively concentrated. Once the data center disaster to occur, would lead to all branches, business outlets and all of the processing standstill, or cause the loss of customer data, the consequences would be unthinkable. Because of a variety of data may be lost, along with people's increasing reliance on network systems, from hardware to software for data protection and backup is the link should not be overlooked. If the user operational systems in place a comprehensive disaster backup / recovery system, when sudden disaster, the key business data systems business losses will be kept to the minimum.From the "IBM white paper" stands in North America that can be analyzed: 90% of stands belonging to the scheme stands, 10% of stands were accidents stands. Of these, more than 50% of downtime may be more than a hour [13]. In order to keeping Chongqing transport industry ensure business continuity, information systems and stable operation to avoid accidents downtime, reducing planned downtime, according to the paper "important information systems disaster recovery guidelines", the general principles of application server cluster, database clusters, redundant network architecture, SAN programs such as storage area networks. I'll design a reliable and effective disaster recovery program for the disaster backup center of Wanzhou.At first , we will identify information systems face the natural and man-made threats, letter recognition system vulnerabilities, threats analysis of the possibilities and quantitative or qualitative description of the possible losses. Interruption impact assessment, disaster recovery analysis system implementation level[18]. Secondly, the traffic system of the various business units of the business functions and the relationship between the determined support various business functions corresponding information systems and other resources, clear information related to the confidentiality, integrity and availability requirements. I use qualitative methods and the interruption of business functions to assess the impact. Under the direction of the business impact analysis and results, identified disaster recovery objectives:①resume critical business functions and priorities;②disaster recovery time frame, or RTO and RPO scope. Second disaster recovery resources in accordance with the costs and risks may cause the loss of balance between the principle of (hereinafter referred to as the "cost risk balance principle")[14] determine the function of each business disaster recovery strategy, including the acquisition of disaster recovery resources and disaster recovery mode grading the specific requirements of the elements. Again on the existing disaster recovery technologies for remote analysis, design systems to meet application of remote data replication technology, network switches and switching application program. The last reference to "important information systems disaster recovery guidelines" Appendix B : disaster recovery plan framework, in accordance with risk analysis and business impact analysis identified disaster recovery, disaster recovery center implementation Wanzhou building units with other relevant contingency plans developed disaster recovery plan.
