Cloud computing can be termed as ’umbrella’ which is used to refer as Internet based development and services. Actually Cloud computing systems represent an emerging technology that provides facilities to its users like storing their files on cloud, access it to large scale, efficient and highly reliable computing systems as pay per use. As valuable and important data of organizations are stored at a remote location on cloud we must be assured that our data is safe and be available at any time. We know that the cloud computing introduces a new type of computing platform in today’s world. This type of computing will generates a large amount of private data on main cloud. Therefore, the necessity of data recovery services are growing day-by-day and it requires a development of an efficient and effective data recovery technique. The purpose of recovery technique is to help user to retrieve information from any mirror server when server lost his data and unable to provide data to the user. To achieve the recovery, many different techniques have been proposed till date. In situations like any hardware malfunction, data may get corrupted or any accidental deletion our data may no longer remain available. To maintain the data safety there must be some data recovery technique for cloud platform to recover valuable and important data efficiently in such situations mentioned above. This paper provides a new technique of data recovery by “Cloud Mirroring”.
