一种基于Winnowing分块的重复数据删除备份与恢复系统设计与实现
Design andimplementation of winnowing based deduplication data backup and recovery system
摘要
Abstract
Aimed at much redundant information of mass data, the authors design and carry out a file backup and recovery system in this article. For achieving the goal of data deduplication , this system applying improved winnowing splits files into blocks with variable length, and combines digest algorithm) index table and compression technology to insure that there is only one copy of every data block saved on the server. The experimental results show that our system can reduce more network traffic than cwRsync. Furthermore, compared with traditional compression techniques, the system has lower disk space occupancy rate.关键词
