I have a Windows tower, a Macbook unibody, and a Macbook pro. I need to back these machines up in a more efficient manner. Currently I have a small external hard drive I use to manually backup important files, but I need something automated, and much bigger. What's the best way to do this? I was thinking about getting a couple 1 TB internal hard drives and installing them into my PC tower for a RAID 1 array. Should I use Timemachine for both the macs and a different app for the Windows machine? Overall, I want to mirror all three computers, and then setup incremental backups for important files such as docs, pics, music, and vids. I'm sort of lost in what all my options are. Any help would be appreciated.
