Brian - The last numbers I have about db entry size is about 700 bytes for a
        base database entry, with a Copy Storage Pool shadow adding some 200
bytes to the entry.  (HSM: 143 bytes + filename length.)  I don't know if
there is any distinction between Backup and Archive types.  You might be
seeing a greater reduction when a backup entry is deleted depending upon your
Versions values in your Copy Group definitions.  It's common to have more
backup images than archive images.
