摘　　要：结合国家级测绘地理信息系统的安全需求,在分析异地容灾技术的基础上,采用存储虚拟化和连续数据保护等先进技术,设计和部署了异地容灾技术方案。结合测绘地理信息业务实际,测算了恢复点目标、恢复时间目标等主要技术指标,分析了本地站点和异地站点间的容灾策略,并对今后的发展方向提出了建议。Aiming to meet the requirements of the national surveying and mapping geographic information system,we propose new technologies for the distributed disaster tolerant.With the help of the technologies of storage virtualization and continuous data protection,we design and implement the framework of the distributed disaster tolerant.Key technological indicators such as recovery point objective and recovery time objective are calculated,and the disaster tolerance strategies of local sites and the remote sites are analyzed.We also suggesitions for future system design.
