I'm currently putting together a dedicated backup server to backup macs and windows pc on. I will use samba for the windows computers (suggest a better options if you know one). I would like to do away with all the permissions so there is never any errors for people accessing the files present. This will be used by my parents who know nothing about permissions etc. Their nearest neighbor is ten to twenty miles away so no worries here. Their wifi is open as well.

Can I just chmod ~/ to the appropriate setting?
Thanks for your time
