Not sure, if you know that, but I think that's called "hierarchical
storage". You could search for that (in combination with "Linux") on the
web, for solutions. Usually, that's $n0000 soft/hardware stuff for big
companies, but there might be cheaper, home-brewn software solutions. I
saw a mention of hierarchical storage support in SGI's XFS, but I didn't
look into it, so I don't know to which extend that "support" goes, but
maybe you find something useful. Tell us, if you did find a good solution.
