Abstract: This paper proposes a multiple layered deduplication system for backup operation in IT environment. The proposed system reduces the duplication in data by using a series of algorithms which are installed with different chunk sizes in descendent order. Our research defines the models and formula for the cumulative deduplication rate and processing time over multiple layers of the system, then, points out the efficiency is heavily affected by how to assign the chunk sizes in each layer in order to achieve the optimal assignment. Finally, the efficiency of the proposal is compared to a conventional single layer deduplication system to assure the improvement.
