Another way came to my mind, cloop (compressed loop device) what
Knoppix and most Live CD uses. It's available here (I think),

	http://developer.linuxtag.net/knoppix/sources/

Backup:

 ntfsclone -o - device | create_compressed_fs - blocksize > cloop.compressed
 
Restore:
  
  install cloop kernel module
  losetup /dev/cloop1 /path/to/file
  ntfsclone --overwrite orig_device /dev/cloop1

I didn't test this but I can't see why it wouldn't work.
