File Permission

Hi Experts,

I need to know in windows server 2008 about the below.

1:- to retain the file or folder level permission in restore case is it neccessary to take system state backup? if we take only file or folder backup and we restore it ..will it take the permission as the time of backup  or we need to enable something?

2:- What will happen if we restore it to another folder (Permissions).?

2:-  what in the same case in Unix and solaris?

Thanks,
