摘要
为了有效解决遥感卫星数据的安全存储问题,该文研究了一种基于网络技术的遥感卫星数据异地备份方法。在充分考虑遥感卫星数据的结构、组成、存储形式和遥感卫星数据备份的特点的基础上,对遥感卫星数据异地备份中的异地备份站点选择、备份数据管理、数据一致性、数据恢复以及备份的创建方法等问题进行了分析,并提出了解决的方法与技术;随后引入了应用系统示例。该应用系统的运行结果显示该文研究的遥感卫星数据异地备份技术可以有效完成遥感卫星数据的异地备份。
This paper presents an approach for network-based remote backup of remote sensing satellite data.With full consideration of structure,composition,storage of remote sensing satellite data and characteristics of remote sensing satellite data backup,some problems such as selection of backup site location,backup data management,data consistency,data restore and backup creation methods are analyzed,and corresponding solutions are proposed.Then an example on the approach is introduced which demonstrates its effectiveness.
