Answer: Set up AWS Storage Gateway to connect with the backup applications using the iSCSI-virtual tape library (VTL) interface.
## Explanation **Correct Answer: D** **Why D is correct:** 1. **AWS Storage Gateway with iSCSI-VTL interface** is specifically designed to replace physical tape libraries with virtual tape libraries in the cloud. 2. **Preserves existing investment** - The company can continue using their existing backup applications and workflows that are designed for tape-based backups. 3. **Eliminates physical tapes** - The VTL interface presents virtual tapes to the backup applications, eliminating the need for physical tape infrastructure. 4. **Cost reduction** - Reduces costs associated with physical tape media, storage, maintenance, and transportation. 5. **Seamless integration** - Backup applications see the Storage Gateway VTL as a standard tape library, requiring minimal changes to existing workflows. **Why other options are incorrect:** **A. AWS Storage Gateway with NFS interface:** - NFS is for file-based storage, not tape-based backups - Would require changing backup applications and workflows - Doesn't directly replace tape infrastructure **B. Amazon EFS with NFS interface:** - EFS is a managed NFS file service for EC2 instances - Not designed for tape backup replacement - Would require significant changes to backup workflows **C. Amazon EFS with iSCSI interface:** - EFS doesn't support iSCSI interface - iSCSI is block storage, not file storage - Not compatible with tape backup workflows **Key AWS Services:** - **AWS Storage Gateway**: Hybrid cloud storage service that connects on-premises environments with AWS cloud storage - **Virtual Tape Library (VTL)**: Presents virtual tapes to backup applications via iSCSI protocol - **Amazon S3**: Backend storage for virtual tapes (Glacier for archival) **Benefits of this solution:** - Maintain existing backup software investments - Reduce physical infrastructure costs - Leverage AWS cloud storage scalability - Enable long-term retention with Amazon S3 Glacier - Improve disaster recovery capabilities
