SAP-C02 Q231 · Storage

Question

A company has an on-premises Microsoft SQL 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 on-premises data center and AWS. Which solution meets these requirements MOST cost-effectively?

Accepted Answer

**Answer A: S3 bucket + Storage Gateway File Gateway with SMB file share**

**Requirement 1: Move backups to S3** → The Storage Gateway **file gateway** presents an SMB file share to the on-premises application. Files written to the SMB share are **automatically stored as objects in S3**. This directly satisfies the requirement of storing backups on S3.

**Requirement 2: Most cost-effective** → The file gateway itself runs as a VM (or hardware appliance) and the primary storage cost is just **S3 object storage**, which is very inexpensive (~$0.023/GB/month for S3 Standard). There is no additional managed file system to pay for. Compare this to FSx for Windows File Server, which charges for provisioned storage and throughput capacity continuously, regardless of usage.

**Requirement 3: SMB
