No, no, no.... no, no!

:-)

There are no hard-links to the original media. The hard links are created
between the different backups.

There are a bunch of hard-links between the different (full) backups you
make, so although you actually have (from a file system standpoint) a view
of each backup as a full backup, you only spend the space on disk once.

sorry if I was unclear.
