Not quite true. User-land "ln" cannot (to my knowledge) create hard
links to directories in OS X. But the file system does support such
hard links. The remote backup program that I use (rsnapshot) definitely
does it, and I suspect that is what Time Machine does under the hood as
well.
There's a lengthy discussion of this matter on Stack Overflow for anyone
interested:

But yes, for your purposes you want a symlink.
