摘要 快照是文件系统的静态只读副本,附网存储中的快照技术可以用于实现文件系统的活备份以及用于恢复被误删除的文件。笔者在设计附网存储的过程中,针对常用的快照技术进行了研究,提出了一种新的设计实现方案,并根据有关的实验数据进行了分析。 Snapshot is a read-only copy of file system,the snapshot in network attached storage can be applied to live backup or recovering removed files.This paper gives a comparison for several implementation of snapshot in the procedure of designing the network attached storage.Then it proposes a new design and implementation for snapshot.Finally,it also provides the experimental data and according analysis.
