Cloud storage is a service model in which data is stored on remote servers, and this data is accessed through the internet. The technique aims to eliminate redundant data segments and keeps a single instance of the data set, even if similar data set is owned by any number of users. Since data blocks are distributed among the multiple individual servers, the user needs to download each block of the file before reconstructing the file which reduces the system efficiency. We propose a server level data recover module in cloud storage system to improve access efficiency. Using the proposed method user can directly fetch the file without downloading each block from the cloud servers. The proposed scheme improves the time efficiency of the system and quick access ability to the stored data. Thus consumes less network bandwidth.
