容灾备份系统研究

目前,计算机网络在现实社会中占据着极其重要的地位,并且计算机系统在企业管理和经营过程中起着至关重要的支撑作用。企事业单位已经开始重视信息的安全性,同时这也是单位决策者最为关心的问题。为保障系统在灾难发生时数据不丢失,能够继续提供服务,容灾就成为保证系统高可靠性的重要手段。如何能够在尽可能短的时间内使系统正常运行,保证数据尽可能少丢失,是容灾技术研究的主要内容。重点分析了容灾与备份的关系、容灾系统的分级、实现方式以及评估标准。

Disaster Recovery Backup System Research

At present, the computer network is occupying the extremely important status in the realistic society, and the computer system is playing the very important support role in the business management and the management process. Enterprises and institutions have started to attach importance to information security. Simultaneously this is also the unit policy-maker most issue of concern. To safeguard system when the disaster occurs the data does not lose, to continue to provide services, disaster recovery has become an important means to guarantee system highly reliable. How can a short period of time as far as possible, enabling the system to normal operation, to ensure minimal loss of data, disaster recovery technology is the main content. This paper analyzes the relationship between backup and disaster recovery, disaster recovery system of classification, the realization of the way and the assessment criteria.
