Backup size is huge! Why? Tech Support

Backup size is huge! Why?

The total size of my overall backup has grown to 931 GB.
 
Data file backup portion grew from 56 to 240 GB and is now 296 GB. 
System Image is 312 GB.
Other files size is 65 GB.
Free space is 257 GB.
 
I understand the 312 GB because that is about the size of my C: drive.
Which does included my data (files, photos, movies).  So I beileve the data potion is
redundant.
I also copy all the data onto other internal and external drives everyweek.
I will not take the data off of the c: drive untill I set up a NAS which is not
for at least a year away.
 
The 'Free space' is what is confusing my why Windows backup needs to backup free space?
 
How can I better backup my computer and files? PLEASE HELP!!! I am out of backup space.
