Here we use deduplication techniques in order to store the files in data center. In deduplication we check a particular file is duplicate or not. If that file is not duplicated then only auditor allow file to store on data center by using different method based file storage. In our project we face challenges on encrypted data storage and management with deduplication. The access control mechanism is also included in this section. Here overall checking of deduplication with heterogeneous data storage management process across multiple cloud service providers with respect to analyzing performance of data center.
