数据容灾技术在重要信息系统中的应用

Technique of Data Disaster Recovery Apply in Important Information System

随着信息化建设的逐步发展,数据库作为整个信息网络化最重要基础组成部分,其地位和作用越来越突出。经权威技术部门统计,影响业务系统宕机的主要原因有:硬件故障占44%、人为错误占32%、软件故障占14%、病毒影响占7%、自然灾难占3%.。上述这些问题都会给信息化的进程造成种种障碍,进一步影响了信息系统连续使用的可用性。为了进一步提高信息系统的可用性、可靠性和安全性,笔者在设计重要信息系统时,把数据容灾作为首要的项目重点进行实施,以保证在任何危机的时刻,信息系统都能保证其业务工作的稳定运转。数据容灾作为高可用性的一部分,在高可用性设计中是必不可少的。容灾建设,就是在复杂的环境中,以保证业务的连续性为目的,根据项目的需求去定制最佳的容灾方案,是一个业务和技术相结合,高度冗余的信息网络化基础组成部分。

With the gradual development of information construction,database as a fundamental part of the most important of the entire information network,and its status and role more and more prominent.By the authority of the technical department of Sta tistics,the main reason affecting the business system downtime: accounted for 44% hardware failure,human error accounted for 32%,the software failures accounted for 14%,the virus affects 7%,natural disaster 3%.These issues will causing all sorts of obsta cles to the process of information,further affecting the continuous availability of information systems.For further information system availability,reliability and security,the author in the design of important information systems,data disaster recovery as the primary focus of the project implementation,to ensure that the information system can guarantee their business work at any moment of crisis,stable operation.Data disaster recovery as part of the high-availability,high-avail ability design is essential.Disaster recovery building,is in a complex environment,in order to ensure business continuity purpos es,according to the project needs to customize the best disaster recovery solution is a combination of a business and technology,the basis of the composition of the information network of highly redundant section.
