Hello, I was wondering if it was possible to install time machine on a separate partition of the main hard drive? I know this is a no-no but heres my reasoning behind it.... Installing 10.5 on my grandma's Mac-Mini and she doesn't keep any documents worth saving, but on her old PC she had to constantly keep reloading windows because of clicking on stuff she shouldn't and of course virus's and spyware (no prob. with that now ) Basically I just want to have a way to easily rollback any settings or retrieve a lost file of some-kind. I would use an external later if she starts keeping pics, music etc... haven't got around to installing it yet but was wondering if its worth a shot.
