Key points
- •File Gateway: NFS/SMB share backed by S3, for file-based applications
- •Volume Gateway: iSCSI block storage backed by EBS, Cached (small local footprint) or Stored (full local copy) mode
- •Tape Gateway: virtual tape library backed by S3/Glacier, for existing tape-expecting backup software
