Migration and Transfer
CoreAWS DataSync
Explicit S3 transfer/performance strategy.
Key points
- DataSync manages repeated data transfers and is distinct from S3 upload mechanics and lifecycle transitions.
Best-known use cases
- D1.3: move a recurring data set when the scenario requires managed transfer scheduling and evidence.
What candidates often confuse it with
- DataSync manages data movement; multipart upload changes large-object upload behavior and S3 Lifecycle changes stored-object class or retention.
Key takeaway
Choose DataSync for managed recurring movement, not for cache, lifecycle, or a one-off upload mechanism.
