I've a Mac that needs to be reinstalled with a new OS, so I'm using time machine to backup my data on my Mac to an external HD. So I can restore my

Data with a fresh OS installation as I've very poor performance speed.


Here's my question , my Laptops HD is 113gbs full , why is time machine only backing up 43Gbs of data ? I assumed it would copy the entire amount.


Does time machine exclude a lot of files ? Is my apps and personal  files only saved ?


Thanks guys
