When you set up a new iOS device or to restore information in one you already have, your iCloud backup makes it easy.
Then, touch a device listed in Backups to see the date and size of your last backup.
For information on manual backup now, see Backup your iOS devices in iCloud. If you do not see a backup that you expected to be there, check out Apple's technical support article.
For help deciding from which backup to restore, including information about the restore from another device backup, see the Apple support article If you can’t back up to iCloud or it could not be restored from the iCloud backup.
After using an iCloud backup to restore or configure a device:
The purchased content is downloaded automatically from the iTunes Store, the App Store, and the Apple books. Some types of content are not automatically downloaded in all countries or regions, and previous purchases may not be available if they have been refunded or are no longer available in the store. See the Apple Support App Store article, the iTunes Store and the availability of Apple Books.
To check if your device information is completely restored, go to Settings> [your name]> iCloud> Storage (or Settings> iCloud> Storage).
If you subscribe to the iCloud Music Library, you can download your songs, albums, and playlists from iCloud once the information on your device has been completely restored.
For information about messages that may appear when restoring information from an iCloud backup, see the Apple support article.
Note: You can restore information on your iOS device from an iTunes backup instead of an iCloud backup. See the topic of the iTunes User Guide Make a backup of your iOS device in iTunes on the PC.
