A financial institution requires an archiving solution for critical data stored on local file servers. The data must be accessible with minimal delay when requested by on-premises users, yet older, less frequently accessed files should be economically archived in the cloud.

Which solution should the architect recommend to meet these needs in a cost-efficient manner?
A managed file transfer service
A fully managed file storage service for Windows files
File gateway mode of a certain hybrid storage service
An online data transfer service
