Abstract: Nowadays, computing devices that rely on a cloud storage environment for data backup, an imminent challenge facing waste of upload bandwidth, storage space due to large amount of redundant data. In this paper, we present Intelligent Backup System, an intelligent data backup scheme that improves data deduplication efficiency by exploiting application awareness, and further combines client and cloud duplicate detection to strike a good balance between cloud storage capacity saving and deduplication time reduction.

Keywords: Data storage, cloud backup, application awareness, effective deduplication.
