Using the Amazon Gateway-VTL in conjunction with NetVault Backup enables seamless data protection of on-premise data to the cloud
The Gateway-VTL is an on-premise disk cache that provides a low-cost, scalable and resilient virtual tape infrastructure. This VTL combines the functionality of a traditional tape library with the low-cost, off-site disk available in Amazon S3 and Glacier. Frequently accessed data is stored locally on the Gateway-VTL and on S3 to provide simple offsite disaster recovery.
As data ages and access demands decline, data is moved from S3 to the Virtual Tape Shelf, which is backed by Glacier. Here data can reside for long periods of time for as little as $0.010 per GB/month.
