AWS Certified Solutions Architect - Professional (#486)

You're running an application on-premises due to its dependency on non-x86 hardware and want to use AWS for data backup. Your backup application is only able to write to POSIX-compatible block-based storage. You have 140TB of data and would like to mount it as a single folder on your file server. Users must be able to access portions of this data while the backups are taking place. What backup solution would be most appropriate for this use case?

Configure your backup software to use S3 as the target for your data backups.
Configure your backup software to use Glacier as the target for your data backups.
