Data is the heart of any organization; hence it is necessary to protect it. For doing so, it is the needed to implement a good backup and recovery plan. But the redundant nature of the backup data makes the storage a concern; hence it is necessary to avoid the redundant data present in the backup. Data de-duplication is one such solution that discovers and removes the redundancies among the data blocks. This paper focuses on giving a wide study on the technology, process and types of the various data de-duplication system.
