How to approach this question
Identify the Storage Gateway types that cache data locally while backing the full dataset in S3: File Gateway and Cached Volume Gateway.
Full Answer
AWS Storage Gateway is a hybrid cloud storage service. File Gateway provides file-based access (NFS/SMB) to S3 with local caching. Volume Gateway (Cached Volumes) provides block storage (iSCSI) where the primary data is in S3, and frequently accessed data is cached locally.
Common mistakes
Choosing Stored Volumes, which require you to have enough local storage for the entire dataset.
