In large scale storage system, data Deduplication has gain more popularity and attention. Data Deduplication storage system, which manages detecting duplicate data and storing data over the nodes. To protect data T-coloring is used .This prevent unauthorized access of data from other users. Deduplication is one such storage optimization technique that avoids storing duplicate copies of data and only one occurrence of the data is stored on storage media. It is essentially a compression method for removing redundant data. As a Space efficient method data deduplication is used in storage system to data backup. Storage space is saved by removing redundant data and also in network storage system the transmission of duplicate data is minimize. Scalability of fingerprint-index search for centralized data Deduplication is main challenge. Fingerprint index is maintained of stored data. Fragmentation of file is done and stored on different nodes. We use fragment placement algorithm for placing the data on different storage node that effectively achieves high level of security in deduplication storage system.T-coloring is used for selecting node to place fragment of particular file
