You might use find with the appropriate options to find all files
changed since a certain time, and feed that list to rsync. Newer
versions of rsync have a --files-from flag, which just takes a list
of files to copy.   

I am curious why you don't want hard links --- I've been using rsync
with hard links to do backups for a while now and it seems to work
well for me. Knowing a bit more about your situation may give us ideas
for you to try.
