Abstract: Online data storage refers to the practice of storing electronic data with a third party service accessed via the Internet. It is an alternative to traditional local storage (such as disk or tape drives) and portable storage (such as optical media or flash drives). It can also be called "hosted storage," "Internet storage". One of the biggest benefits of online storage is the ability to access data from anywhere. As the number of devices the average person uses continues to grow, syncing or transferring data among devices has become more important. Not only does it help transfer data between devices, online data storage also provides the ability to share files among different users. This paper presents the different techniques which help in making online storage an easier way of storing data. Data deduplication is one of important techniques for eliminating duplicate copies of repeating data, and has been widely used in online storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication,we have also proposed an encryption technique which helps in encrypting the data before storing it. Our approach to deduplication ,encryption and compression in online storage aims at reduction in storage space and efficient use
