Abstract
Data centers backup using a cloud service is a significant operation that saves the data from being lost. It reduces the costs and optimize the hardware provisioning level. Software defined networking (SDN) is a growing network paradigm which divides the usual monolithic control and data plane found in the classical network paradigm. It improves and simplifies the network management process. This research addresses a specific problem in SDNs regarding Quality of Service (QoS) target achievement in backup operations between data centers (inter-site). This fundamental backup activity has special QoS requirements. The aim of this article is to provide a new cost-efficient inter-site backup model for cloud networks using the SDN technique. It helps in choosing a path to perform the backup in the current network according to customer's and provider's requirements, while taking the QoS parameters into consideration simultaneously, in order to achieve an efficient-cost solution.
