Backing up only windows 7, not free space

[TheArchitect77]

I am planning on making a windows 7 image with macrium reflect free. Windows 7 is installed on a 290 GB partition. Now, only 22.3 GB of that space is being used, pretty much by windows 7 and other third-party programs. Will macrium reflect back up that 22.3 GB or back up all 290 GB which is mostly free space? ( I know that the question seems a little weird, but I want to make sure)

It will back up the 22.3.

The image file it creates will be somewhere around half that size.

Be sure to make and fully test the recovery boot CD you make within Macrium.
