Improving the Performance of System in Cloud by Using Selective Deduplication

Cloud Computing is very popular today because of large amount of data storage and fast access of data over the network. But in today' s scenario we find the some issue to access and store data in cloud likewise data theft, data loss, privacy issue, infected application, data location, security on vendor level, security at user level and data duplication. As we find of recent study 7 Zeta Byte (ZB) data available in different storage location after 5 years it will increases the 5 times more data storage. For the better performance of system we use the different data deduplication method liked selective performance oriented data deduplication. In this paper we propose to remove data redundancy from available offline or online data storage as well as we provide security of data which helps to improve the performance of system. After deleting the data from file automatically size of file reduces and which helps to reduce the traffic on the network.
