摘要
遥感数据异地备份是在数据中心和备份端各自保存一份遥感数据,并提供数据恢复手段的容灾技术。遥感数据异地归档是遥感数据异地备份的基本组成部分,是实现遥感数据异地备份的关键。为实现遥感数据异地备份中异地归档功能,本文针对异地归档过程中的难点和问题,提出了遥感数据异地归档方法,并从技术角度出发提出解决方案。
The remote sensing data remote backup（RSDRB） is a kind of disaster recovery technology,which saves the remote sensing data both in the data center and backup station and provides a means of data recovery.The remote archiving method of remote sensing data is an essential component of RSDRB and key to implement RSDRB.To achieve remote archiving function of RSDRB,this paper presents the remote archiving method of remote sensing data.Then this paper analyses the method and puts forward solutions of the difficulties and problems in the process of remote archiving.
