Hi, I'm considering purchasing a Time Capsule, but have a few questions first. 1. Can I backup windows and mac on the same time capsule, or does it only support mac? 2. If so, do the mac/win files end up in different "apartments" of the disk, or are they joined in the same file structure and can be accessed from both win and mac? 3. Can I attach an external harddrive (formatted HFS+) to the Time Capsule, and have it used to mirror the Time Machine backup on the Time Capsule (so the data is backed up in two places)? 4. Is it possible to split the one usb-input to the Time Capsule with a usb-splitter so that I can attach two devices at the same time (in my case, two harddrives)?
