You are right. So there is no complete preservation of meta data. 
Though I would still defend that there is a way to do it. It just 
hasn't been done in rdiff :-)

Full OS backup that you can be restored into a bootable state is 
VERY hard to do though. At the very least you'd need to make sure
that the partition's/disk's boot record is also restored and put
into the right spot.

Also when done from within the windows system there are always files
that are locked by the operating system and most Windows backup
programs use the "Volume Shadow Copy Service" to work around those
