Question
A company has an application that analyzes and stores image data on premises. The application receives millions of new image files every day. Files are an average of 1 MB in size. The files are analyzed in batches of 1 GB. When the application analyzes a batch, the application zips the images together. The application then archives the images as a single file in an on-premises NFS server for long-term storage. The company has a Microsoft Hyper-V environment on premises and has compute capacity available. The company does not have storage capacity and wants to archive the images on AWS. The company needs the ability to retrieve archived data within 1 week of a request. The company has a 10 Gbps AWS Direct Connect connection between its on-premises data center and AWS. The company needs to set bandwidth limits and schedule archived images to be copied to AWS during non-business hours. Which solution will meet these requirements MOST cost-effectively?

Why each option
To archive zipped image batches from an on-premises NFS server in a Hyper-V environment to AWS, with a 1-week retrieval requirement and a 10 Gbps Direct Connect, the most suitable solution is to deploy an AWS DataSync agent as a Hyper-V VM on premises. This agent can then efficiently transfer data from the NFS server to Amazon S3 Glacier Flexible Retrieval, leveraging the existing compute capacity and meeting all storage, retrieval, and connectivity requirements.
Deploying an AWS DataSync agent on an Amazon EC2 instance in AWS is incorrect because DataSync agents are designed to be deployed *on-premises* to facilitate data transfer *from* on-premises storage. A GPU-based instance is also unnecessary.
Deploying an AWS DataSync agent as a Hyper-V VM on-premises is the correct approach for efficiently transferring files from an on-premises NFS server to AWS. DataSync is optimized for large-scale, high-performance data migration and replication. Configuring it to transfer data to Amazon S3 Glacier Flexible Retrieval provides a cost-effective long-term archiving solution that easily meets the requirement of retrieving data within one week.
Similar to A, deploying the DataSync agent on an EC2 instance in AWS is incorrect for transferring data from on-premises NFS.
An AWS Storage Gateway Tape Gateway is designed to integrate with existing backup applications that utilize tape-based storage and is not the appropriate service for direct file migration from an active NFS server.
Concept tested: On-premises to AWS file transfer, archiving, storage gateway selection.
