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
