I'm start backup my Mac mini 2012 with TM in 04/10/13 when I was on 10.8. Now I'm on 10.10 (I did upgrade via Mac App Store) and after year and half I want to start from scratch. After reformat the system I'll be able to restore some specific files from TM backup? I prefer to make this transfer by myself (the manual way) and not let some app doing it for me. suggestion anyone?
