In the following question, the answer says AWS CLI and Volume Gateway Stored Mode. Given that the question says, "without moving it to other storage first" that eliminates Volume Gateway Stored Mode as that would require me to move data from the file server to the Storage Gateway before it goes to S3. Am I missing something? Gateway Cached might make a little more sense as it would just land in the upload buffer and get sent straight to S3.
— Question —
You want to gradually migrate data directly from an on-prem RAID10 file server to S3 without moving it to other storage first. Which of these would you use? (Choose 2).
Storage Migration Service
Storage Gateway – Volume Gateway Stored Mode
Storage Gateway – Volume Gateway Cached Mode
There is a little-known feature for Storage Gateway-Stored Mode (or Stored Volumes as they now call it) to preserve the data on the existing volume. We would not be adding a new mount point, but you would mounting the existing volume from the Storage Gateway.
