Seeing as it knows nothing about filesystems, and everything about 
partitions, it will treat the partition as an opaque blob and move it as 
a single object ...

You would think so :-)

I use ext4, and make heavy use of hard links. Last time I tried a 
straight copy (not backup/restore) I think the copied partition would 
have been three times the size of the original - that is if it hadn't 
run out of space first :-)

But it sounds like that would work well for you.

Cheers,
