Abstract: Aiming at the storage management problem of archival data, this paper proposes the AStore archival storage architecture. The data storage and management strategy for the archival storage system is designed by using data fingerprint, data compression, data chunk-dividing and data de-duplication technologies. It tests and analyzes the storage system performance different parameters. Experimental results demonstrate that the strategy can reduce the data redundancy, improve the space utilization efficiency and access performance of the storage system.

Key words: archival storage, data fingerprint, data de-duplication, data compression

摘要： 针对归档数据的存储管理问题，提出一种归档存储体系结构AStore，采用数据指纹、数据压缩、数据分块和重复数据删除技术，设计归档存储系统的数据存储和管理策略。测试并分析不同参数设置下存储系统的性能，结果表明该策略能减少数据冗余，提高系统存储空间的利用率和访问性能。
