I have Windows 7 and Fedora Linux in my system. I want format the system completely. So how to take back up of both OS and their partition easily? I'm preferring to do the backups of both OSes from Fedora itself? So is it possible? If so, How?

You can use
dd to copy the disk sectors directly to a file on a removable drive, but you shouldn't copy a running system that way. Some of the files will be in use and the filesystem could get corrupted. It would be safer to boot to a Live CD and do the copy from there. Alternatively, though a little more challenging, you could remount your root partition read-only:
mount -o remount,ro /
...and then do the
dd copy, but most of your running daemons won't tolerate a read-only filesystem.
