A university research laboratory needs to migrate 30 TB of data from an on-premises Windows file server to Amazon FSx for Windows File Server. The laboratory has a 1 Gbps network link that many other departments in the university share.
The laboratory wants to implement a data migration service that will maximize the performance of the data transfer. However, the laboratory needs to be able to control the amount of bandwidth that the service uses to minimize the impact on other departments. The data migration must take place within the next 5 days.

Explanation
AWS DataSync is the correct solution for this scenario because:
-
Optimized Data Transfer: AWS DataSync is specifically designed for migrating large amounts of data to AWS storage services. It uses a parallel, multi-threaded architecture to maximize network utilization and transfer performance.
-
Bandwidth Control: DataSync allows you to configure bandwidth throttling to control the amount of network bandwidth used during data transfers. This is crucial for the laboratory's requirement to minimize impact on other departments sharing the 1 Gbps network link.
-
FSx for Windows Support: DataSync natively supports Amazon FSx for Windows File Server as a destination, making it ideal for migrating from on-premises Windows file servers.
-
Time Constraint: With 30 TB of data and a 1 Gbps link (theoretical maximum of ~125 MB/s), the transfer could theoretically complete in about 2.8 days if using full bandwidth. However, with bandwidth throttling to share the link, DataSync can still complete within the 5-day requirement while controlling impact on other users.
Why other options are incorrect:
- A. AWS Snowcone: This is a physical device for offline data transfer, which doesn't meet the requirement to use the existing network connection or allow bandwidth control during transfer.
- B. Amazon FSx File Gateway: This provides hybrid storage access but isn't optimized for large-scale data migration with bandwidth control.
- D. AWS Transfer Family: This is for managed file transfer protocols (SFTP, FTPS, FTP) but isn't designed for large-scale Windows file server migrations with bandwidth throttling.
Key Features of AWS DataSync:
- Automatic encryption of data in transit
- Data integrity validation
- Incremental transfer capabilities
- Detailed monitoring and logging
- Bandwidth throttling configuration
- Support for Windows file servers and FSx for Windows
