Abstract: This project is for hybrid storage architecture, to make use of both shared-nothing and shared-disk architectures. The user can either upload file or can just synchronize the original copy from the master computer synchronized before. All the changes made on the original file will be reflected on the file stored on server. All files stored on the cloud server are broken into packets of some definite size and these packets will be distributed on various hard disks this data are replicated using the RAID-1 concept, which are merged as a whole again whenever the user makes an access to the file on the on-line copy or makes changes to the original copy which is synchronized with the application. The packets are encrypted using a block of ECB encrypted cipher text; all the blocks are dependent on all the previous blocks.
