What happens when you approach the five gigabyte limit on Apple's new iCloud service?
Reportedly automatic backup will pause until you either delete content or purchase more space on the mostly free service.
The problem is how much more space will cost on Apple's cloud has not been released yet. Once users fill their cloud, they will be directed to the iCloud settings and told to purchase more storage.
But there is a silver lining in Apple's cloud. Content purchased from Apple's App Store or from iTunes doesn't count against the cloud data quota.
