摘要: 通过浙江省测绘地理信息成果档案异地灾备系统建设实践,在分析测绘地理信息成果档案备份现状、需求和容灾级别的基础上,对异地灾备系统架构、容灾技术方法进行研究,提出在政务外网、涉密内网两种网络环境中测绘地理信息成果档案容灾系统的设计模型,重点介绍了在线数据分别通过NexentaStor、DataGuard和分布式文件系统(DFS)实现同步或异步复制的技术,以及离线数据异地备份的维护情况。这种在线容灾和离线备份相结合的综合灾备方案可供测绘地理信息同行借鉴。

Abstract: This paper examines the case for Zhejiang offsite disaster recovery center for surveying, mapping and geoinformation archives based on the status quo of its backups, requirements and the levels of disaster recovery. It also discusses the frameworks and techniques of the center and comes up with two design models for disaster recovery systems based on external and internal networks respectively. Much attention goes to how online data are replicated synchronously and asynchronously via NexentaStor, DataGuard and DFS, as well as the maintenance of offsite data remote backups. The combination of online disaster recovery and offsite data backup would provide a comprehensive plan for surveying, mapping and geoinformation professionals.

Key words: surveying and mapping, archives, offsite backup, disaster tolerant
