基于内容地址存储的文件级备份系统
File Level Backup System Based on Content-addressed Storage
【摘要】 针对当前备份系统存在的重复数据量大、网络传输数据多、数据安全性低等特点,提出一种新的文件级备份系统。该系统构建于Bacula开源备份系统基础之上,使用磁盘作为存储介质,基于内容地址存储,采用重复删除技术以节省存储空间。性能测试结果表明,该系统能有效缓解存储和网络传输的压力,同时提高数据的安全性。
【Abstract】 For problems of current backup system,such as large amount of duplicate data,too many data transmit over the network,and low data security,this paper presents a new file level backup system,which is built on the open source Bacula backup system.It uses the disk as a storage medium,based on content-based addresses to store data,and carries out de-duplication technology to save storage space.Performance test results show that the system can effectively ease the pressure on storage and network transmission,while improving data security.
