Azure Import/Export Service allows you to securely transfer large amounts of data to Azure blob storage by shipping hard disk drives to an Azure data center. You can also use this service to transfer data from Azure blob storage to hard disk drives and ship to your on-premises site. This service is suitable in situations where you want to transfer several TBs of data to or from Azure, but uploading or downloading over the network is not feasible due to limited bandwidth or high network costs.
