Deduplication Based Storage and Retrieval of Data from Cloud Environment

  Gopinath kowdeed,  Mr S.Pradeep

Data deduplication is a method used for reducing the amount of storage space a company needs to save its data. Most of the organizations, contains the storage systems that contain duplicate copies of many blocks of data. For example, the same file may be saved in different places by the different users, or two or more files that aren't same may still include much of the same content data. Deduplication obviates these extra copies by saving just one copy of the data and replacing the other copies with pointers that guide back to the original data copy. Organizationas frequently use deduplication in backup and disaster recovery applications, but it can be used to clear up the space in primary storage as well. To abviate this duplication of data and to maintain the confidentiality in the cloud, the concept of twin cloud is introduced. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption method has been proposed to encrypt the data before outsourcing.
