[comp.sys.mac.misc] smart copy/update program

BACKGROUND: I work on certain documents on more than one Macintosh.
This involves keeping the current version of those documents on
floppies.  But for data security, I also want to keep copies of the
files on the computers' hard disks.  (And sometimes a file that I end
up working on in various places gets its start on a hard disk.)
Updating the various disks becomes a headache.  Which brings me to the

QUESTION:
Is there a copying utility for the Mac that can be told to overwrite
only OLDER versions of a file?  The Finder's copy routine warns you
about overwriting files, but gives no clue about whether the one about
to be overwritten is older, newer, or the same as the one about to
overwrite it.  I would like a copying or updating program that could
be told to overwrite all older files, or one that, when it warns you
about potential overwriting, displays the timestamps and sizes of the
two relevant files, so that you have some basis on which to answer the
question. 

Does such a thing exist?
