I use a home grown rsync based backup process (for 15+ years).
When traveling or otherwise worried about large directory tree
renames, I will sometimes do a 'cp -rpl' instead of a rename. This
will allow rsync to notice the new hard links and it just create the
new directory structure without transferring the data again. After
the rsync is complete I can then remove the original directory tree
and rsync again. The rsync needs to use --hard-links for this to
work.
I only recommend doing this if you understand and are comfortable with
hard links and rsync.
