Up until last week I've kept a backup for my iPhone on my harddrive, as have everyone else. I have the 16GB iPhone 4 and my backup is about 10 gigs in size. But now since there is iCloud backup in "the cloud", could I just remove that old backup on the hard drive and free up that space or how does it work? 10 gigs is not much on my 1TB iMac but I've been thinking about selling it and just sticking with a 128 GB macbook air, and then 10GB certainly is a lot more. Am I correct or how does it work?
