Question

A media company is designing a new hybrid backup solution. On-premises servers generate approximately 8 TB of new media files daily that must be archived to AWS for long-term retention. The on-premises applications require low-latency read access to recently written files (last 30 days) via an NFS mount, while older files can tolerate retrieval times of several hours. The company wants to minimize on-premises storage footprint and needs a recovery point objective (RPO) that ensures data written locally is asynchronously uploaded to AWS. Which solution BEST meets these requirements?

Accepted Answer

Deploy an AWS Storage Gateway File Gateway with an NFS share backed by S3, apply an S3 Lifecycle policy to transition objects older than 30 days to S3 Glacier Flexible Retrieval, and rely on the gateway's local cache for low-latency access to recent files.

Answer

Deploy an AWS Storage Gateway Volume Gateway in stored volume mode, take EBS snapshots to S3, and use S3 Lifecycle rules to move snapshots to S3 Glacier Deep Archive after 30 days.

Answer

Mount an Amazon EFS file system over AWS Direct Connect to the on-premises servers and configure EFS Lifecycle Management to move files to EFS Infrequent Access after 30 days.

Answer

Use AWS DataSync to copy files nightly to Amazon S3, then present the S3 bucket to on-premises servers through an S3 File Gateway configured with write-back caching disabled.
