Bad plan, this does not give you everything.

Expected behaviour. This can never work. Windows is very picky
about what modes and attributes the system files have, whether their
names are in WIN32 & DOS namespace or POSIX namespace, etc, etc.
NTFS-3g will neither read nor write any of these features and even if
it did rsync would not know about them thus it would not backup/
restore them. Thus your backup method cannot work. If you want to
do what you do you would have to only backup your files then on the
new disk install Windows from scratch and then put your files back
(note NOT Windows files only the data files you added).

No full backup would be no use either. You have to use ntfsclone if
you want to be able to restore it. Just copying the files cannot work.

I think I have answered that already... Yes you did something
obviously wrong. You did not use ntfsclone to do the backup...
