Description

Our paper presents a data recovery system which rectifies a disaster in cloud. Cloud computing provides a wide range of online storage where security issues play a major role. In existing system, Cloud computing not providing the security on data and only provide data recovery process. In existing system, data recovery process implement on finding the failure cloud server and then recover the failure server data but recover data was not checking this is actual data or not. In proposed system using new algorithm(SHA1) to improve the more security to user file. The user file is splitted into small data pieces and stored with multiple servers connected to a cloud. When single server is under failure and user requests for data retrieval, then recover the data with another servers. Using k means clustering algorithm for splitted data. Using Recovery proxy Data from failed server is retrieved from the metadata which is maintained by cloud Finally check the actual MAC key with retrieve MAC key.
