When a migration or disaster recovery project must be used, hybrid storage solutions must be evaluated, and that is where the storage gateways come to the rescue. With virtualization methods, you can drop in a storage solution that is compatible with your existing products. It is imperative that the cloud solution can be integrated with on-premises drivers and standard storage protocols, like NFS v3, v4.1, and iSCSI. You can use local caching capabilities and security with SSL and AES 256.
You can use a storage gateway as a disaster recovery strategy for continuous incremental backups failing over to the cloud.
