Cloud Computing Failures, Recovery Approaches and Management Tools

Fault tolerance is a major concern in clouds in order to guarantee the reliability and the availability, also the data backup and recovery is one of the most important issue in cloud computing environments, and the need of efficient techniques for the data recovery are increasing by the days. When the server can't provide the data for the users or the data has been lost because of one of the different kinds of failures the data recovery techniques used to retrieve the data from the backup server. This paper illustrated the cloud computing failures, recovery approaches and management tools.
