摘要
介绍天基信息技术、天地一体化网络技术和数据容灾技术的发展现状,论述基于天基信息基础设施的数据容灾方案的可行性,提出了基于Hadoop的HDFS分布式文件管理机制构建数据容灾框架,并给出了通用的容灾策略。同时,提出采用云存储解决天基信息基础设施资源受限的问题,通过高速星地链路解决数据同步复制问题,利用天基热备份控制节点解决在重大自然灾害时数据服务不间断提供问题。
The present situation and development of space-based information technology, integrated spaceground network technology and data disaster recovery technology is described, and a scheme for data disaster recovery and a common strategy based on HDFS also given. And cloud storage is proposed to solve the problem of limited space resource, high-speed space-ground data link to solve the problem of date synchronous replication, and Namenode replication in the space-based infrastructure to solve the problem of uninterrupted date service when the major natural disaster occurs.
