Disk for Time Machine
I considered to start to use Time Machine for a total backup of my two iMac's. Is it possible to use one external HD on one of the computers and share it to the other one? And how shall I think about size? If I today have one machine with 1,7 TB data on a 2 TB HD and the other one has 0,45 TB date on a 1 TB disk.
