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.
