The problem with duplicate files is that a lot of the time they'll look
like duplicates but will not in fact be that way. Take for instance an
application that is 'customised' by the installation process to work only
on a single machine.  It has an IP number, Ethernet address or Name to
distinguish itself.   Stashing only one copy of photoshop say, because
they all have exactly the same file size, would not work.  It's possible
that even checksumming might not work because it's conceivable that the
checksum is 'padded' after the customisation process to match the original.

The interim way around not backing up multiple copies of data is to not
back it up at all.  If it's in multiple places and easily installable,
why not exclude the entire directory, or certain file specs.  Another
option is to have application areas and data areas on the client.  Never
backup the application areas and always backup the data areas.
