Replace Tape Backup with Cloud Storage:                                                         Tape media management, media costs, 3rd party offsite contracts, and the sheer volume of data growth makes tape backup challenging in any organization. The AWS Storage Gateway service offers a Tape Gateway configuration that gives you an alternative to physical backup tapes that fits seamlessly into your existing backup process. Now you have the local performance of disk, a low-cost highly scalable cloud back-end, and minimal disruption to existing systems.

Storage Solution:  File gateway, volume gateway or tape gateway.  File gateway : File gateway can be used to ingest files to Amazon S3 which can be used with object-based workloads, and to provide cost-effective storage for traditional backup applications. They can also be used to bind on premise file storage with S3. Data can be cost-effectively, and durably stored and retrieved from Amazon S3 with the help of industry-standard file protocols.   Volume Gateway:  Storage volumes can be created in the AWS Cloud. The on premise applications can be used to access the data in these volumes in the form of iSCSI targets. This can be done using cached and stored volumes.  Cached volumes  are used to store volume data in AWS that will have a portion of most recently accessed data in the on-premise cache. This method makes sure that the low-latency access feature is enabled to access the frequently accessed dataset. Seamless access to the entire dataset stored in AW...
