Does anybody know how to, or if a single Time Machine drive can be used to back up more than one computer? I'd like to consolidate my Time Machine backups to just one FW800 drive. The drive is already setup as the Time Machine drive for my desktop, how can I get my laptop to also back up to this drive? I've tried to just select that drive through the Time Machine application on the laptop, but it doesn't seem to want to back-up to a shared drive. I also tried adding the shared laptop drive as a 'non-excluded' drive from my desktop's Time Machine application, but that isn't working either. Does anybody have one network Time Machine drive for multiple computers? Thanks?
