iCloud and iTunes (on your laptop or desktop) can backup most data on the iPad. iCloud is a suite of Internet-based (also known as the cloud) services from Apple. With up to 5GB of free storage, it includes backup of email, contacts, and calendars, and automatic synchronization of content (photos, videos, and documents) between compatible devices.
Backed-up information may include purchased music, TV shows, and books; photos and video in the Camera Roll; device settings (for example, Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts); app data; app organization; iMessages, ringtones, and more. Music and video purchased using iTunes are synced from your computer but are not backed up. These can be restored by syncing with iTunes using your computer.
Automatically Backup using iCloud:
iCloud automatically backs up the most important data on the iPad. Once enabled, it will run on a daily basis as long as your device is:
- Connected to the Internet over Wi-Fi
- Connected to a power source
- Screen locked
To enable iCloud backup:
Go to Settings > iCloud > Backup & Storage turn iCloud Backup on
Manually backup using iCloud:
When connected to the Internet over Wi-Fi go to Settings > iCloud > Storage & Backup and by choosing Back Up Now.
How to backup using iTunes on your computer:
- Using the included USB cable, connect the iPad to a computer with the latest version of iTunes installed.
- In most cases iTunes will begin sync and backup of the iPad automatically. NOTE: iTunes will not backup automatically when you connect the iPad to your computer if you have selected iCloud (above) as your backup method.
- If sync and backup do not begin automatically after connecting your iPad, open iTunes and under Devices right-click (or control-click) the iPad’s name and select Back Up.
