A. AWS DataSync Explanation: AWS DataSync is a managed data transfer service that simplifies and accelerates moving large amounts of data online between on-premises storage and Amazon S3, EFS, or FSx for Windows File Server. DataSync is optimized for efficient, incremental, and reliable transfers of large datasets, making it suitable for transferring 5 TB of data with daily updates.

AWS DataSync: Purpose: AWS DataSync is designed for automated, efficient, and secure data transfer between on-premises storage and AWS storage services like Amazon S3. Key Features: Automates and schedules data transfers, supporting periodic syncs. Handles incremental transfers, only copying changed or new files (ideal for the 5% daily changes). Supports multiple file formats and preserves metadata. Provides encryption for secure transfers. Scales to handle large datasets like 5 TB and optimizes transfer performance. Why it fits: DataSync meets all requirements by automating periodic transfers, efficiently handling incremental updates, and supporting diverse file formats with minimal operational overhead.
