What is File and S3 Archive Gateway Software?

Archive Gateway software acts as mechanism to store data to technologies that are not normally supported directly. Data is written using Cloud (S3) or File (SMB or NFS) protocols to the gateway and from there data is rewritten to one or more technologies including tape, VTL, optical, NAS, public or private Cloud. Content is often written through a fast cache, which maintains all metadata associated with the file or object along with any data required to access it in the future.
