Q703. A company has NFS servers in an on-premises data center that need to periodically back up small amounts of data to Amazon S3.Which solution meets these requirements and is MOST cost-effective?

Correct Answer: B. Set up an AWS DataSync agent on the on-premises servers, and sync the data to Amazon S3.

Explanation

To meet the requirements of periodically backing up small amounts of data from NFS servers in an on- premises data center to Amazon S3 while being cost-effective, the recommended solution is:B. Set up an AWS DataSync agent on the on-premises servers, and sync the data to Amazon S3. Option B provides a cost-effective solution that meets the requirements:- Set up an AWS DataSync agent: AWS DataSync is a data transfer service that simplifies and automates data movement between on-premises storage and AWS storage services. By installing a DataSync agent on the on-premises servers, you can securely and efficiently transfer data to Amazon S3.- Sync the data to Amazon S3: With the DataSync agent in place, you can configure tasks to periodically sync the small amounts of data from the NFS servers to Amazon S3. DataSync uses efficient data transfer techniques, such as data deduplication and incremental transfers, to optimize the transfer process and reduce costs.Option A, setting up AWS Glue to copy the data from the on-premises servers to Amazon S3, is not the recommended solution for this scenario. AWS Glue is a fully managed extract, transform, and load (ETL) service that is designed for processing and transforming large datasets. It is not specifically tailored for small periodic backups and may incur higher costs for the data transfer.Option C, setting up an SFTP sync using AWS Transfer for SFTP to sync data from on-premises to Amazon S3, is not the most cost-effective solution. While AWS Transfer for SFTP provides a secure file transfer solution, it may incur additional costs for data transfer and maintenance of the SFTP server. Option D, setting up an AWS Direct Connect connection between the on-premises data center and a VPC, and copying the data to Amazon S3, is not the recommended solution for this scenario. AWS Direct Connect is a dedicated network connection between on-premises and AWS, primarily used for high- bandwidth and low-latency access. It is not necessary for periodic small backups and may add unnecessary costs and complexity.Therefore, the most cost-effective solution to meet the requirements of periodically backing up small amounts of data from NFS servers in an on-premises data center to Amazon S3 is B: Set up an AWS DataSync agent on the on-premises servers, and sync the data to Amazon S3. This solution provides an efficient and cost-effective way to transfer the data while leveraging the capabilities of AWS DataSync for data movement.
