In contrast, tiering is akin to a specialized librarian permanently in place to move one file at a time into a unique filing system for which only the librarian knows how to get each file back. Tiering is essentially another name for hierarchical storage management (HSM). Tiering or HSM solutions have been tried in multiple forms over many years, and inevitably, they tend to cause more pain than benefit.
NAS cloud gateways provide a global file uae rcs data system and, therefore, global access via the public cloud to files traditionally stored in on-premises NAS storage systems. Since the NAS gateway device maintains all file-related metadata in its global file system, it can be claimed to serve as an archive front-end.
But while the NAS gateway considers the content archived, it is not true archiving because the metadata is stored in the NAS gateway so any access to that data in the event of recall is arbitrated by the gateway (very similar to tiering).
Both tiering and gateways present companies with an important concern. What if that solution gets decommissioned or the vendor goes out of business? How do you retrieve data when the app is no longer available?
