A Survey on Data Migration Techniques Across the Cloud Storage Systems

In cloud computing, the data could be stored anywhere across the globe, and it limits the client organisations to have less control over the stored data. In cloud computing, it is seen many times that user data is altered, deleted or modified. A data migration technique is adapted by users to have better security services like third party auditor, to ensure that their data is safe on the cloud. So there is need of more secure mechanism to migrate the data over the cloud and hence several mechanisms have been proposed. This paper presents the literature survey related to data migration techniques available across the cloud storage systems.
