Actually...it's probably worse than that.  That 600 bytes/file refers to
the first copy of the file resident on the TSM server.  Each additional
copy takes ~200 bytes.

If you dig back in the archives for this list, you'll finde references
indiacting (I believe) that you should probably "split up" your TSM
servers when your DB gets to about 50GB or so.
