It is said that backup only backup's real data, but... I have 800GB partition with 10GB on it, backup did make a 7GB image, but the image is restoring 5 hours

Now is the backup restoring only the data or sector by sector? 5 hours is too much for 10GB of data. I tried it on 400GB partition and it took only 3 hours, so I guess it is size dependent.
Can you "fix" this?
One wishlist that has something in common. I have 10 GB data and partition size is 50GB yet when doing backup the size was 100GB. Now I can not restore partition to 50GB sized partition although only 10GB data is in the archive. That also suggest that the R-DRIVE is doing sector by sector.
That 2 connected problems make life a lot harder using it

Other than that I find the program great!
