AWS Storage Gateway Volume Gateway represents the family of gateways that support
block-based volumes, previously referred to as gateway-cached and gateway-stored mode
AWS Storage Gateway Volume Gateway operates in 2 modes:
- Stored Volume mode – the entire dataset is stored on-site and is asynchronously backed up
to S3 (EBS point-in-time snapshots). Snapshots are incremental and compressed
- Cached Volume mode – the entire dataset is stored on S3 and a cache of the most frequently
accessed data is cached on-site
AWS Storage Gateway File Gateway provides a virtual on-premises file server, which enables
you to store and retrieve files as objects in Amazon S3
Multi-part upload and transfer acceleration are features of S3 associated with uploading
files directly to S3
