Topic 1 Question 158
A company is running an application on premises and wants to use AWS for data backup. All of the data must be available locally. The backup application can write only to block-based storage that is compatible with the Portable Operating System Interface (POSIX).
Which backup solution will meet these requirements?
Configure the backup software to use Amazon S3 as the target for the data backups.
Configure the backup software to use Amazon S3 Glacier as the target for the data backups.
Use AWS Storage Gateway, and configure it to use gateway-cached volumes.
Use AWS Storage Gateway, and configure it to use gateway-stored volumes.

Stored volumes make your entire data available locally on the gateway, while maintaining an asynchronous copy in the S3 bucket. Cached volumes store the full volume in the S3 bucket, while only keeping the recently used data in local cache.

https://docs.amazonaws.cn/en_us/storagegateway/latest/vgw/StorageGatewayConcepts.html By using stored volumes, you can store your primary data locally, while asynchronously backing up that data to Amazon. Stored volumes provide your on-premises applications with low-latency access to their entire datasets. At the same time, they provide durable, offsite backups.
