摘　　要：嵌入式系统工作文档的备份/恢复是一个具有较强实用性的课题,相对于普通计算机,嵌入式系统的应用程序必须占用较少的系统资源。嵌入式系统中,由于工作文档在内存中以内存页为存储单位进行存放,而在闪存中以磁盘簇为存储单位进行存放,所以文章设计并实现了基于块数据的工作文档备份/恢复系统,该系统在实际运行中具有性能高,占用系统资源少的优点。The working documents＇ backup/recovery in embedded system is a practical issue, compared to the ordinary computer, the application in embedded system must take up less system resources. In embedded system, because the working document store in memory by memory- page, and in flash memory by disk-cluster, this paper designs and implements the working documents＇ backup/recovery system based on the block data, which has the advantages of high- performance and occupied less system resources.
