What is a Tape Gateway, and how does it help organizations modernize their existing backup processes that rely on physical tape systems?

Intermediate

Answer

A Tape Gateway presents a virtual tape library interface that works seamlessly with existing backup software already configured to write to physical tape drives, meaning organizations can continue using their familiar backup software and processes exactly as before, while Storage Gateway transparently stores those virtual tapes in S3 and can archive older tapes into extremely low cost Glacier storage, eliminating the need to physically manage, transport, and store actual tape media.

Real-world example A company using long established backup software that only knows how to write to physical tape drives adopts a Tape Gateway, continuing to use the exact same backup software and scheduled jobs while eliminating the physical tape management burden entirely.
