I need some help with a hard drive strategy. I have a MBP SR 2.2 with the 120 GB internal. I use leopard, and time machine is working wonderfully. But I need more. The original plan was to spring for Super Duper and two 120 GB portable external drives to do a rotation of clone drives. The idea being keep one at home, keep one at a friend's house, back up once a week and switch drives. Here's the hitch: I only about 20 GB free on the MBP drive (do mostly to a media library that keeps increasing). The way I see it I have two good options: 1) Proceed as planned above with the two external hds and super duper, and transfer some of my lesser played music, pictures and comic books to a third harddrive.; or 2) Buy an internal HD (maybe 250GB) for the MBP. Then get two 250 portables and do my rotating backup plan. My big concern here is that I will void my Apple Care by replacing the HD. I would appreciate any comments or suggestions as to what is the best move here, maybe even a third option. Thanks.
