Data consolidation is a challenging issue in data integration.The usefulness of data increases when it is linked and fused with other data from numerous (Web) sources.The process of eliminating the repeated or duplicates copies of data is called as Data deduplication.Modern backup storage systems adopt deduplication to save space by eliminating data duplicates whereas impairing the storage reliability.As the world moves to digital storage for archival purposes, there is an increasing demand for systems that can provide secure data storage in a cost-effective manner.This data deduplication process is widely used in in cloud storage to decrease storage space and upload bandwidth.By using, deduplication system progress of storage utilization and reliability is increases.In addition, the dare of privacy for sensitive data also take place when they are outsourced by users to cloud.Planning to address the above security test, this paper constructs the first effort to celebrate the idea of scattered reliable deduplication system. This paper recommends a new distributed deduplication systems with upper dependability in which the data chunks are distributed from corner to cornering multiple cloud servers. The safety needs of data privacy and tag stability are also accomplish by introducing a deterministic secret sharing scheme in distributed storage systems, instead of using convergent encryption as in previous deduplication systems. A deduplication technique, on the other hand, can reduce the storage cost at the server side and save the upload bandwidth at the user side.I.
