it would be inconvenient to make a dedup copy on harddisk or tape, you
could only do it as a ZFS filesystem or ZFS send stream. it's better to
use a generic tool like hardlink(1), and just delete files afterwards
with
find . -type f -links +1 -exec rm {} \;
(untested! notice that using xargs or -exec rm {} + will wipe out all
copies of your duplicate files, so don't do that!)

perhaps this is more convenient:
