Hi, I have a 500GB Seagate GoFlex external drive which I'll be using for backup and have a couple questions. #1. How much space do I need for Time Machine? I have 320GBs of space in my MacBook Pro, but about 225GBs is free. So I partitioned the drive so that Time Machine gets 250GBs. Is that too much or not enough? #2. Can I move the Time Machine files to my MacBook Pro's hard drive, reformat the external drive so that the Time Machine partition is larger, then move the Time Machine files back to the larger partition and still work just like it was before? Thats if I started to runout of space. #3. There is a base station for my external drive that will link it up to my router allowing it to be a network drive. So I was wondering if it will be able to backup Time Machine wirelessly? Thanks.
