Storage sizes don't add up!

I'm backing up less than 32GB of data to the Acronis cloud.

Here, Acronis reports I have 172 GB free (i.e. that I am using supposedly using 78GB)

And here, Acronis reports 23% of my 250GB limit is used (i.e. 57.5GB)

What is the additional 25GB or 46GB of storage being used for?

And my network stats monitor indicates that 45GB has been sent to you via your trueimagehomeservice.exe, when I only had 32GB of data to be backed up:

Can someone please explain all of this?
