Question

A company has an on-premises Microsoft SOL Server database that writes a nightly 200 GB export to a local drive. The company wants to move the backups to more robust cloud storage on Amazon S3. The company has set up a 10 Gbps AWS Direct Connect connection between the onpremises data center and AWS. Which solution meets these requirements MOST cost-effectively?

Accepted Answer

**Answer A: S3 bucket + Storage Gateway File Gateway + SMB file share** satisfies every requirement cost-effectively:

1. **Robust cloud storage on S3**: A file gateway presents an SMB file share to the on-premises application, but the actual data is stored **directly in Amazon S3** as objects. This is exactly what the company asked for.

2. **Cost-effectiveness**: Storage Gateway file gateway has no ongoing compute costs beyond the gateway VM itself. The primary cost is S3 storage, which at ~$0.023/GB/month for S3 Standard is far cheaper than provisioned file systems like FSx. For 200GB nightly backups, S3 lifecycle policies can further reduce cost by transitioning older backups to S3 Glacier.

3. **SMB compatibility**: SQL Server on Windows writes to a local drive. A file gateway SMB sha
