New Windows 10 computer has 452 GB capacity hard disc and 40 GB are used.  What could I expect a backup image file to be if I use the free editions of Macrium Reflect, or AOMEI Backupper, or EaseUs Todo?  Will a backup image be the whole 452 GB hard drive, or will the backup be of the used 40 GB only?

Being that the default on all programs mentioned use normal compression and backup data only the image will be something less than 40 GB.

As implied earlier, full images normally do not backup empty byte-space -- unless one is doing sector-by-sector full imaging.

A good indication of what to expect comes from what I tried and found when done for the Windows Vista machine.  78 GB of used space on the hard disc became 30 GB of backup file image.  I had never yet tried this when I first asked the question.

I just checked my Laptop and using Acronis for Image Backup.

My C:\Drive shows 28G used and my Image is 22G.

 

So most apps will very slightly but some compression does take place.

I run Macrium Reflect regularly, and I have a 500gig SSD main drive. I do complete image backups, and usually fall between 129 - 131.7 gigs. I had only one 248.7 gig backup, but I had a lot of vacation pictures loaded at that time. Graphics and music compress poorly, so if you have a lot of those the backup size will be larger.
