Hi!
I know this may be stupid, but...
I'm backing up my linux kernel trees, and found out that backup (done
by rsync) is twice as big as original. That's quite bad... it is
because git uses hardlinks heavily but rsync can't preserve them.
I'm pretty sure someone hit this before... what is the trick?
Pavel

$ rsync --help | grep "preserve hard links"
-H, --hard-links preserve hard links

Why can't rsync preserve them? Doesn't 'rsync --hard-links' work?
(however, it can only work if you rsync all paths at once so rsync
gets to see that the inodes match)
