Ahh, rsync and hard links, the choice of the discerning gentleman-

rsync -H is a notorious memory-hog. However, if you're brave enough to
upgrade to rsync 3, then rsync eats far less memory. No idea if that
still holds for -H, but it's worth trying. What else did you try?
The obvious choice is dump/restore if the two FSes are the same type.
