Windows Migration Tool for Hierarchical Storage Management?

A not-so Anonymous Coward would like to bring this query to your attention: "The company I work for is in the process of implementing an Hierarchical Storage Management (HSM) solution for our ever-growing Departmental and Users data. I'm looking for a tool that has the functionality to move data from our NAS to a WIN2000 Server while leaving a link in the original location pointing to the new location. The WIN2000 server is using an HSM product to move the files from that server to tape after a period of time, to be recalled at a later point when required. If possible the tool would have the ability to filter files based on an exclude and an include list, file size, and last access date. Does such a tool exists for a WIN2000 environment or is there a better way to accomplish this?"
