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.

Explanations:

Amazon S3 is object storage, not block storage. It is not POSIX-compatible.

Amazon S3 Glacier is an archival storage service and does not support block-level access.

Gateway-cached volumes only store data in AWS, not locally. The data would not be available locally.

Gateway-stored volumes store a copy of the data both in AWS and locally, ensuring POSIX compatibility and local access.
