Use ATI 2011 in Windows 7?

I just bought ATI 2011. I am currently using the Backup and Imaging features built into Windows 7 Pro.

Is there any point in installing ATI 2011? What can ATI do that Windows 7 imaging cannot?

For the most part, I intend to use ATI for boot-time imaging only. I don't want to use the continuous backup and GUI part of ATI.

Thanks.
