I get confused about my MDF and LDF files against backup files

My MDF and LDF files sizes are like 100 MG each one
We bakup the database always. When we do this, we get 5 txt files with information about the backup
one BAK file with size like my MDF file, but we get another BAK file that have a BIG size, like 8 GB
What happened hereI assume that you mean 100 MB, and not 100 MG.
Remember that when you backup a database, and you always use the same backup
file names, the backup files are appended onto the existing files unless you
use the INIT option. That may explain why the other file is so big. To
view the contents of each backup set within that file, use the RESTORE
HEADERONLY command.
