1: Settings
On your iPad or iPhone go to your Settings app and then tap on the iCloud icon which appears about half way down the list of options. Now tap Storage & Backup near the bottom.
2: Turn it on
At the bottom of this new screen is the iCloud Backup button. Turn it on. You’ll need to be on Wi-Fi in order to actually start the backing up process. It won’t work for iPhone owners over 3G.
3: Say bye to wires
A warning will pop up telling you that once the wireless backup option is in place, you’ll no longer need to rely on the backup happening when connected physically to iTunes.
4: Give it time
You will now see the above alert and may have to wait a while for the first backup to take place. Once that is done, future backups will be quicker as they will only include incrementally added data.
