Connect your on-premises IT environment with AWS’s storage infrastructure for data backup and disaster recovery

What is AWS Storage Gateway?

The AWS Storage Gateway is a service connecting an on-premises software appliance with cloud-based storage. Once the AWS Storage Gateway’s software appliance is installed on a local host, you can mount Storage Gateway volumes to your on-premises application servers as iSCSI devices, enabling a wide variety of systems and applications to make use of them. Data written to these volumes is maintained on your on-premises storage hardware while being asynchronously backed up to AWS, where it is stored in Amazon Glacier or in Amazon S3 in the form of Amazon EBS snapshots. Snapshots are encrypted to make sure that customers do not have to worry about encrypting sensitive data themselves. When customers need to retrieve data, they can restore snapshots locally, or create Amazon EBS volumes from snapshots for use with applications running in Amazon EC2. It provides low-latency performance by maintaining frequently accessed data on-premises while securely storing all of your data encrypted.

AWS Storage Gateway is a tool in the Data Backup category of a tech stack.

AWS Storage Gateway's Features

  • Gateway-Cached Volumes – Gateway-Cached volumes allow you to utilize Amazon S3 for your primary data, while retaining some portion of it locally in a cache for frequently accessed data.
  • Gateway-Stored Volumes – Gateway-Stored volumes store your primary data locally, while asynchronously backing up that data to AWS.
  • Data Snapshots – Gateway-Cached volumes and Gateway-Stored volumes provide the ability to create and store point-in-time snapshots of your storage volumes in Amazon S3.
  • Gateway-VTL – Gateway-VTL provides you with a cost-effective, scalable, and durable virtual tape infrastructure that allows you to eliminate the challenges associated with owning and operating an on-premises physical tape infrastructure.
  • Secure – The AWS Storage Gateway securely transfers your data to AWS over SSL and stores data encrypted at rest in Amazon S3 and Amazon Glacier using Advanced Encryption Standard (AES) 256, a secure symmetric-key encryption standard using 256-bit encryption keys.
  • Durably backed by Amazon S3 and Amazon Glacier –The AWS Storage Gateway durably stores your on-premises application data by uploading it to Amazon S3 and Amazon Glacier. Amazon S3 and Amazon Glacier redundantly store data in multiple facilities and on multiple devices within each facility. Amazon S3 and Amazon Glacier also perform regular, systematic data integrity checks and are built to be automatically self-healing.
  • Compatible – There is no need to re-architect your on-premises applications. Gateway-Cached volumes and Gateway-Stored volumes expose a standard iSCSI block disk device interface and Gateway-VTL presents a standard iSCSI virtual tape library interface.
