Cloud computing is the very hot topic in recent years. It is said to be the subsequent immeasurable thing in the world of computer after the internet. Cloud computing is the type of Internet - based computing which provides the online storage. No matter where the users are or which computers the users use, it enables the cloud users to put their data into the cloud. User can store and get the data placed in the cloud provided that it connects to the Internet. In cloud computing, very large amount of data is generated in electronic form. The cloud storage providers are responsible for keeping the data avail able and accessible to the user at any cost. When data is distributed, it is stored online at different locations increasing the risk of unauthorised physical access to the data. The service providers must provide security to the user’s data. Also there is risk of data losses. So there is necessity of data recovery services in the cloud. To maintain the data integrity, we need to provide security. In this paper, we focus on cloud data storage security, which has always been a key feature of quality of servi ce. We propose a secured data back - up technique for cloud computing in this paper. The two objectives are achieved by proposed technique, first it helps the users to recover their data files if the cloud is destroyed due to any reason and second is to prov ide the security to user data during storage on main cloud by using RC6 encryption algorithm. We have also provide the compression technique to store the back - up of data. Thus the time and storage related issues are also being solved by proposed techniques
