AWS DataSync is a fully managed data transfer service that simplifies moving large amounts of data between on-premises storage systems and AWS services. It can also transfer data between different AWS services, including different AWS Regions. DataSync provides a simple, scalable, and automated solution to transfer data, and it minimizes the operational overhead because it is fully managed by AWS.

Selected Answer: A
• AWS DataSync is a data transfer service optimized for moving large amounts of data between NFS file systems. It can automatically copy files and metadata between your NFS file systems in different AWS Regions. • DataSync requires minimal setup and management. You deploy a source and destination agent, provide the source and destination locations, and DataSync handles the actual data transfer efficiently in the background. • DataSync can schedule and monitor data transfers to keep source and destination in sync with minimal overhead. It resumes interrupted transfers and validates data integrity. • DataSync optimizes data transfer performance across AWS's network infrastructure. It can achieve high throughput with minimal impact to your operations.

Option B - AWS Snowball requires physical devices to transfer data. This incurs overhead to transport devices and manually load/unload data. It is not an online data transfer solution. Option C - Setting up and managing an SFTP server would require provisioning EC2 instances, handling security groups, and writing scripts to automate the data transfer - all of which demand more overhead than DataSync. Option D - AWS Database Migration Service is designed for migrating databases, not general file system data. It would require converting your NFS data into a database format, incurring additional overhead.
