Norton Ghost Image Seemed Too Quick

Hi...I just created a Ghost Image by going to "Tasks" / "Run or Manage Backups"/  "Define New Backup Job ".

I have about 65 gigs of used space on my C Drive which has a capacity of 500 gigs. The image file that Ghost created ended up being 31.6 gigs in size and it only took approx. 6 or 7 minutes to complete.

My friend who has Norton Ghost as well said his backups usually take about 45 minutes or so to complete and he thinks maybe I didn't do it correctly. Does it seem abnormal for me to complete the image which was compressed using the default

setting of "Normal" within 6 to 7 minutes ? By the way I'm using the latest version of Ghost 15.0 and my computer has an i3 dual core processor and 12 gigs of ram. Thanks in advance for your help.
