Ive had my mac now just short of a year almost (blackbook, core duo 2ghz, 2gb ram) Im running leopard on it, but what i wanted to upgrade to snow leopard in a weeks time. My question is i was gonna do a upgrade in order not to lose my files and all. What im wondering is can i make a backup of my stuff even if i dont have a external hdd? What i was gonna do is make a backup and store i on my desktop pc (windows xp) and leave it one of those partitions. Or would be more beneficial to me to do a clean install, but i still want to get all my files back and my setup. I guess im not quite sure how to do the backup.
