File Recovery Technique using Mirroring concept in Cloud as Storage as a Service

Abstract

Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network. The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud Computing entrusts remote services with a user’s data, software and computation. It represents an emerging technology that permits the user to store big amount of data in cloud server and can use whenever required from anywhere. It provides various kinds of services to its users such as SaaS, IaaS, and PaaS. Storage-as-a-service is also a service delivered by cloud infrastructure in which big amount of data can be stored in cloud. As valuable and vital data of enterprises are stored at a remote location on cloud so we must be assured that user’s data must be safe and be available at any time. In situations like hardware failure, data corruption or any accidental deletion our data may no longer remain available. To maintain the data security and we need a data backup technique for cloud platform to recover valuable and vital data efficiently. The purpose of recovery technique is to help user to retrieve information from any mirror server when main server lost his data and unable to provide data to the user.
