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.
Key words:
de-duplication technology,
content-addressed storage,
variable length segment,

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。
