Existing users, 
I am not (yet) an iDefrag user, and my knowledge/understanding of defraging/optimization is nil, so I well understand if my question is off base.
SuperDuper allows me the option to erase a drive/volume prior to copying the backup. Doesn’t the erasing accomplish the same thing?
I know iDefrag has more bells and whistles (some are of no benefit to me) and it may defrag faster, but as I use/schedule SuperDuper while I sleep, I see no advantage there.
So for folks such as me, why use iDefrag?
No offense is intended to the developers, I just don’t understand.

iDefrag vs. SuperDuper - june8
iDefrag has many algorithims to defrag, optimize your files and/or metadata. If you want to erase all your drive and copy your files from scratch every time even when you need to defrag just a bunch of files, it is up to you to use a backup/restore utility for this purpose.Friday, October 02 2009 @ 06:05 PM PDT

Just to clarify my post. Superduper is the best cloning soft out there. But it will copy a bad disk to a clean disk. That is why it is so good. It does what it says it will do. It will not optimize or rearrange files. It is a mirror copy.Reply to This
