Use Tape Gateway to replace physical tapes on premises with virtual tapes on AWS—reducing your data storage costs without changing your tape-based backup workflows. Tape Gateway supports all leading backup applications and caches virtual tapes on premises for low-latency data access. It compresses your tape data, encrypts it, and stores it in a virtual tape library in Amazon Simple Storage Service (Amazon S3). From there, you can transfer it to either Amazon S3 Glacier Flexible Retrieval or Amazon S3 Glacier Deep Archive to help minimize your long-term storage costs. https://aws.amazon.com/storagegateway/vtl/#:~:text=Use-,Tape%20Gateway,-to%20replace%20physical

Tape Gateway enables you to replace using physical tapes on premises with virtual tapes in AWS without changing existing backup workflows. Tape Gateway supports all leading backup applications and caches virtual tapes on premises for low-latency data access. Tape Gateway encrypts data between the gateway and AWS for secure data transfer, and compresses data and transitions virtual tapes between Amazon S3 and Amazon S3 Glacier Flexible Retrieval, or Amazon S3 Glacier Deep Archive, to minimize storage costs.
