Disk Utility Restore vs SuperDuper!

[dan]

Boy I'm really confused. I tried to find the answer on the net before I cloned my internal drive but couldn't find a clear answer. I am on 10.5.7. I used Disk Utility's restore to partition my external drive and used a partition map scheme of "GUID partition table". Then I used Restore to copy my internal hard drive to the external drive. When it was done both disks had the same amount of used space and I was able to boot off of the new external drive. And as far as I could tell all my files were there - music, videos, and other files. So as far as I could tell using Disk Utility Restore or SuperDuper! to clone the drive was equivalent. I know I can't use Disk Utility to do an incremental backup which is what I think Smart Update is and I know you can do that with SuperDuper!. But are you saying that Disk Utility's Restore doesn't do a byte-for-byte copy whereas SuperDuper!'s cloning does? Thanks in advance for amplifying your answer!
