Sorry for HTML.
I don't know or much care about rsync, but certainly, if an application is =
to be a *backup* application it should reinstate hard links. Two hard link=
s to a file are semantically not the same as two copies of the file, so if =
you back the things up (and presumably restore them) separately you may bre=
ak stuff. You should back up a single copy (plus its hard links) and resto=
re likewise (one file, multiple names).
To do this I imagine you would use the inode number of the file (or similar=
concept in other filesystems, e.g NTFS file id); if you're backing up an i=
node you've already backed up then you know you just need a hard link, not =
a full copy.

or is it ok if I then create a hardlink after backing only one instance of=
Also how does rsync treat hardlinks after backing up data.
