%Is there such a thing available as unix source?  What I need is a

make a timestamp file
run find on your your filesystem looking for files newer than timestamp
let the result of the find be an argument to tar as filename
and tar cBf - $filename | (cd /newplace;tar xpBf -)
When you're done touch timestamp

Then you're ready for next time.
