Let’s say that I have a 1 TB drive that is 1 TB big. After running the backup what size would the file be? I know it’s not going to be 1 TB. 400 GB, 500 GB? What size?

Kenneth, welcome to these public User Forums.

Sorry but impossible to guess what the backup size would be as it depends on what the actual used size of data on the 1TB drive is, what type of files are included, how compressible those files are etc.

Typically, Acronis will achieve around 20% compression of standard OS programs / files but not for files which are already in a highly compressed state such as videos, images, music etc.
