I apologize for what is probably a long explanation for a silly question... I just ordered a refurbished MBA ultimate to replace my 2006 12" white Macbook (2 GHz core duo, 1 GB RAM, 60 GB HD, running OS 10.4). As you might imagine, my needs are pretty simple - I'd say 84% web browsing, 10% word processing, 3% light Photoshop, 2% iMovie editing, 1% powerpoint presentations. I'm going to get a new display to go with it (maybe ACD?) in a month or so after we move. The reason I got the new computer is I am going to start recording videos for work through an S-video to USB adapter cable. I will probably record 5-8 videos of 1-2 GB each every week. So I have to carry it around more so hence the MBA. These mainly just have to be archived, not accessed frequently with only minimal editing if we decide to put together a project. I have a 500 GB Western digital "my passport" portable USB drive that I got for back up of my Macbook and some overflow of nonessential stuff. Ideally, I'd like to use the WD drive for my work videos and maybe my photo archive and then have a separate external drive for backing up both the MBA hard drive and the video hard drive. And leave these connected to the display on my desktop. What is the best system for setting this up? How can I accomplish backing up from 2 drives (one external and one internal) onto the same drive without much hassle? And if it will look nice on my desk that's a big plus too!
