省级测绘电子档案存储机制及安全策略的研究

Research on Storage Mechanism and Security Policy of Provincial Geomatics Electronic Archives

结合省级测绘电子档案的特点与主流存储介质的优缺点,提出了基于磁盘阵列、硬盘、磁带、光盘的多介质多级存储机制。合理的优化了测绘电子档案的存储结构,制定了载体保护策略、运行安全策略、数据备份恢复策略与再生性保护策略,为测绘电子档案安全存储提供了支撑保障。

Combined with the characteristics of provincial geomatics electronic archives and the advantages and disadvantages of the main storage medium,proposes a multi media multi level storage mechanism based on disk array,hard disk,magnetic tape and compact disk.Reasonable optimization the storage structure of geomatics electronic archives,the carrier protection strategy,the operation security strategy,the data backup and recovery strategy,the regenerative protection strategy are developed,provide support for the safe storage of geomatics electronic archives.
