Fulll backup not backing up files.

I am new to backWPup & backing up in general, I am using the backup to dropbox option, and it is working for db files, db files and WP export xml. But when I choose to do db files, WP export XML, and Files, it says it was successful and the zip uploaded to dropbox, but it was just marginally bigger than my backup that was just db files and export html. That cant be right?

My files on the job summary screen says:
DB Size: 193.02 MB
Files Size: 4.63 GB

Here is the log file contents:
