What would you recommend for an HSM product for use with NetApp? I am interested in a product that will periodically scan my file systems on my filers and then, based on criteria that I establish, move those files to an R200. I would like for it to leave a link in place of the original file so that it can be retrieved should it be needed. I would like to be able to further refine the management such that once a file has been moved to the R200 for some period of time let me know to either archive it to tape/DVD/etc and then delete it from the R200 and remove the links.
