How do I know what items are being backed up in the iCloud backup of my iPad?
1. Tap on "Settings".
2. On the left-hand menu tap "iCloud" and then on the right-hand menu tap "Storage".
3. Tap "Manage Storage".
4. If you have multiple devices using the same iCloud account you will see those devices listed here with how much of the storage space it is taking up. To look at the specifics for this iPad tap on the same of the iPad.
5. Tap "Show All Apps".
6. Here you will see all of the apps that include data in the backup. To turn a specific app off just tap the switch. This does not affect the ability to use the app at all. It just does not store any data in the backup of the device. Typically the Photo Library is the largest consumer of data.
