The PoINT NetApp FAS Agent of PoINT Storage Manager performs a transparent migration of files according to configurable rules. Thereby, files migrated from the NetApp FAS systems are replaced by so called “Stubs” (references) and stored safely by PoINT Storage Manager on second level storage, e.g. a Blu-ray Disc (BD) jukebox. This concept especially fulfils the “single path” requirement, so that no changes in the applications are necessary.
