TeraCopy Backup

I use TC not only to copy files, but also to backup entire directories. It extremely fast when backing up full directories, only grabs the new or changed files. We use Cobian for our daily backup. It completely copies all files to the backup drive, this can be very time consuming. Don't get me wrong, Cobian is a very good program. 

It would be great if the TC engine could be adopted to work like a backup program.  If TC only updated or copied new files, it would be lightning fast. It could be scheduled and set up as a backup program. 

I would purchase "TC Backup" in a New York Second. 

Thanks for the review.
