What is Included in iCloud Backup?
While both Automated and Manual iCloud Backups are easy to make, you need to be aware that an iCloud Backup is not a complete backup of iPhone.
According to Apple, an iCloud Backup includes only the data available on the local storage of your device and does not include data that is already available on iCloud.
This means a typical iCloud Backup includes Device Settings, App Data, Purchase History, Home Screen Layout, Ringtones and Apple Watch Backups.
Text Messages, Photos and Videos will be included in iCloud Backup, only if iCloud Messages and iCloud Photos (respectively) have not been enabled on your device.
What is Not Included in iCloud Backup?
As you can see from above list, an iCloud Backup of your iPhone does not include Apps, Music, Books, Movies that you may have downloaded to iPhone from App Store, Apple Music and other sources.
You will be able to re-download purchased Apps, iBooks, Movies and Music from iTunes & App Stores. However, you won’t be able to get back Apps, Music and Books downloaded from other sources.
As far as Photos, Videos and iCloud iMessages are concerned, they will be back on your device as soon as iPhone Syncs with iCloud.
Note: If you are looking for a complete backup of iPhone, you can Backup iPhone to Windows Computer.
