iCloud backups are encrypted automatically so that your data is protected from
unauthorized access both while it’s transmitted to your devices and when it’s
stored in iCloud. If you’re using iTunes for your backup, select “Encrypt iPad
backup” in the iTunes Summary pane.
Manage your backups.
Go to Settings > iCloud. You can manage which apps are backed up to iCloud
by tapping them on or off. Go to Settings > iCloud > Storage > Manage Storage
to remove existing backups and manage iCloud Drive or Documents & Data. In
iTunes, remove backups in iTunes Preferences.
View the devices being backed up.
Go to Settings > iCloud > Storage > Manage Storage.
Stop iCloud backups.
Go to Settings > iCloud > Backup, then turn off iCloud Backup.
Music not purchased in iTunes isn’t backed up in iCloud. Use iTunes to back up
and restore that content. See Sync with iTunes.
Important: Backups for music, movies, or TV show purchases are not available
in all countries. Previous purchases may not be restored if they are no longer in
the iTunes Store, App Store, or iBooks Store.
Purchased content, iCloud Photo Sharing, and My Photo Stream content don’t
count against your 5 GB of free iCloud storage.
