Migration and Transfer
AWS DataSync
AWS DataSync accelerates online movement of files and objects between on-premises storage and AWS storage services. It can seed or refresh a large RAG corpus while preserving selected metadata and verifying transferred data.
Key points
- Agents connect supported on-premises storage to the service
- Tasks schedule transfer, filtering, verification, and bandwidth limits
- Incremental runs copy detected changes rather than every byte
When to use it
- Migrate a network file share into an S3 knowledge source
- Refresh model artifacts from on-premises storage on a controlled schedule
Exam tips
- Choose DataSync for managed bulk online transfer and Transfer Family for partner-facing file protocols
- A successful byte transfer does not validate document classification or permission mapping
