Storage Gateway Overview

• Connects an on-premises software appliance with cloud-based storage to provide seamless integration with data security features between your on-premises IT environment and the AWS storage infrastructure.

File Gateway

• Enables you to store and retrieve objects in Amazon S3 using file protocols such as Network File System (NFS) and Server Message Block (SMB).

• Objects written through File Gateway can be directly accessed in S3.

Volume Gateway

• Provides block storage to your on-premises applications using iSCSI connectivity.

• Data on the volumes is stored in Amazon S3 and you can take point in time copies of volumes which are stored in AWS as Amazon EBS snapshots.

• Cached volumes

  • Store your data in Amazon S3 and retain a copy of frequently accessed data subsets locally.

  • Retain low-latency access to your frequently accessed data.

• Stored volumes

  • If you need low-latency access to your entire dataset, first configure your on-premises gateway to store all your data locally.

Tape Gateway

• Provides your backup application with an iSCSI virtual tape library (VTL) interface, consisting of a virtual media changer, virtual tape drives, and virtual tapes. Virtual tapes are stored in Amazon S3 and can be archived to Amazon S3 Glacier or Amazon S3 Glacier Deep Archive.

• Provides cloud-backed virtual tape storage.

• With a tape gateway, you can cost-effectively and durably archive backup data in GLACIER or DEEP_ARCHIVE.

  • A tape gateway provides a virtual tape infrastructure that scales seamlessly with your business needs and eliminates the operational burden of provisioning, scaling, and maintaining a physical tape infrastructure.
