I'm trying to determine the best backup and recovery plan to use for 2 iMacs and one PC. Currently have a Time Capsule for one iMac but it's just one TB and the older iMac has a 1 TB HDD and 3 years old. I just bought a new Time Capsule that's 3 TB but how do I partition the new Time Capsule so each iMac can backup to the same new Time Capsule? The new iMac is the 768 GB SSD version so I'm thinking it too will only need a 1 TB partition? What do you think? Cloud based backup is appealing if it's automated and doesn't slow my systems down when everything is running. Should I use both Time Capsule as well as Crash Plan +?
