Backup &/or Image???

Would someone look here
http://www.nero.com/enu/support-nero7-helpfiles.html

at Nero BackItUp2

and tell me if this program (which I have) will backup my OS, either by backup or image?


Also, on the page of supported files it does NOT list NTFS as being supported by the imaging function.
As I read through the help file I was unclear on what this program will actually do.

Again, can I use this program for a backup of my OS, or only just my data? Factor in that for the most part once I have a backup of the OS it won't change much over time.

 

Just realised this should have gone under software not hardware!
