Cloud computing is a model for enabling for on demand network access to shared configurable computing resources (e.g. networks, servers, storage, applications and services). It is based on virtualization and distributed computing technologies. Cloud data storage systems enable user to store data efficiently on server without any trouble of data resources. User can easily store and retrieve their data remotely. The two biggest concerns about cloud data storage are reliability and security. Clients aren't like to entrust their data to another third party or companies without a guarantee that they will be able to access therein formations whenever they want. In the existing system, the data are stored in the cloud using dynamic data operation with computation which makes the user need to make a copy for further updating and verification of the data loss. Different distributed storing auditing techniques are used for overcoming the problem of data loss.
