Need advice on backup plan for new iMac Well, the 768 GB SSD iMac should be delivered this week! I currently have my 2010 1TB iMac on time machine backup to my 2010 time capsule via wireless. I'm also obviously using the WiFi for my 2010 iMac, iPhone, Macbook Pro, iPad and Macbook Air. I'm only backing up the iMac to the time capsule. So with the new 768 GB iMac coming should I get a new larger time capsule like the 2 TB or 3 TB and also take advantage of it's somewhat better signal strength via WiFi as well as backup both iMacs to a new, larger capacity time capsule? Or should I backup the new iMac via USB3 or Thunderbolt to an external wired hard drive separate from my current 1 TB time capsule and continue to use the WiFi for all computers without getting a new larger capacity time capsule?? What would you guys do?
