Data deduplication techniques

With the information and network technology, rapid development, rapid increase in the size of the data center, energy consumption in the proportion of IT spending rising. In the great green environment many companies are eyeing the green store, hoping thereby to reduce the energy storage system. Data de-duplication technology to optimize the storage system can greatly reduce the amount of data, thereby reducing energy consumption and reduce heat emission. Data compression can reduce the number of disks used in the operation to reduce disk energy consumption costs. By studying the data de-duplication strategy, processes, and implementations for the following further lay the foundation of the work.
