Overwhelmed the data loss problem, data can be massed transversely multiple parts in numerous regions with compound servers. Records which can be misplaced, their segment are stated and that portion is restored. This paper extant a literature review pastures of cloud computing with a focus on data loss in cloud storage. Thus the segments of the records which are misplaced could be identified and that portion is restored.
