Question

A manufacturing company must migrate 450 TB of historical sensor data from an on-premises NAS to Amazon S3. The remote facility has a single 100 Mbps internet connection that is also used for daily business operations and cannot be saturated. Management requires the data to be in S3 within 30 days, and the facility will remain operational (the NAS continues to be read/written during the migration window). Which approach best meets the requirements while minimizing impact on the production network?

Accepted Answer

Order multiple AWS Snowball Edge Storage Optimized devices to bulk-transfer the 450 TB, then use AWS DataSync over the internet link to capture only the incremental changes made during the transfer window.

Answer

Use AWS DataSync over the existing 100 Mbps link with bandwidth throttling to copy all 450 TB directly to S3, scheduling transfers during off-hours.

Answer

Set up AWS Storage Gateway in file mode and let it asynchronously upload all 450 TB to S3 over the internet connection over the 30-day window.

Answer

Order a single AWS Snowmobile to transfer the 450 TB and ship it to the nearest AWS Region for ingestion into S3.
