AWS Storage Gateway Documentation
AWS Storage Gateway is a hybrid cloud storage service that is designed to give you on-premises access to cloud storage.
Key features
Standard Storage Protocols
Storage Gateway is designed to connect to your local production or backup applications. Its protocol conversion and device emulation enables you to access block data on volumes managed by Storage Gateway on top of Amazon Simple Storage Service (S3), store files as native Amazon S3 objects or in fully managed cloud file shares with Amazon FSx for Windows File Server. You can keep virtual tape backups online in a virtual tape library backed by S3 or move the backups to a tape archive tier.
Cache
The local gateway appliance is designed to maintain a cache of recently written or read data so your applications. The gateways are designed to use a read-through and write-back cache, committing data locally, acknowledging the write operations, and then asynchronously copying data to AWS.
Data Transfer
AWS Storage Gateway is designed to provide secure upload of changed data and secure downloads of requested data, encrypting data in transit between any type of gateway appliance and AWS using SSL. Storage Gateway is designed to deliver end-to-end protection of customer data from the Storage Gateway in the enterprise network to the data residing in AWS.
Gateway Types
Amazon S3 File Gateway
Amazon S3 File Gateway presents a file interface that enables you to store files as objects in Amazon S3 and access those files from your data center or Amazon EC2, or access those files as objects directly in Amazon S3. Once objects are transferred to S3, they can be managed as native S3 objects and bucket policies, and can be applied directly to objects stored in your bucket. Amazon S3 File Gateway is also designed to publish audit logs.
Customers can use Amazon S3 File Gateway to back up on-premises file data as objects in Amazon S3 and for hybrid cloud workflows.
Tape Gateway
Tape Gateway presents an iSCSI-based virtual tape library (VTL) of virtual tape drives and a virtual media changer to your on-premises backup application. Tape Gateway is designed to store your virtual tapes in Amazon Simple Storage Service (Amazon S3) and creates new ones.
Volume Gateway
Volume Gateway presents your applications' block storage volumes using the iSCSI protocol. Data written to these volumes can be asynchronously backed up as point-in-time snapshots of your volumes, and stored in the cloud as Amazon EBS snapshots. You can back up your on-premises Volume Gateway volumes. Volume backups are designed to be stored as Amazon EBS snapshots in AWS. These snapshots are designed to be incremental backups that capture only changed blocks. Snapshot storage is also designed to be compressed.
Storage Gateway Deployment Options
As a hybrid cloud service, AWS Storage Gateway is designed to be managed and consist of both cloud and on-premises components, which can be deployed in several methods based on your on-premises infrastructure needs.
Storage Gateway is designed to provide service endpoints with options to deploy and connect your gateway to Storage Gateway.
