Deduplication technology is widely used to eliminate duplicate data and save resources in storage systems of modern data centers. However, from the energy point of view, deduplication cannot always achieve good energy efficiency for storage systems. In this paper, we propose an energy-aware deduplication strategy for backup tasks to achieve the balance of the process in terms of energy consumption, backup throughput and deduplication ratio. Experiments have been made on different datasets to verify the effectiveness of the new strategy.
