Q: How do I close an app that is in my backup list for iCloud?

Hi, WMHammonds.  

Thank your visiting Apple Support Communities.  

I understand you want to turn off the option to backup application data to iCloud.  Here is the article that will walk you through that process.  

Select which iOS apps to back up

Many apps automatically back up to iCloud after you install them. You can change which apps back up to iCloud and remove existing backups of that app's data from your storage.

Use these steps on your iPhone, iPad, or iPod touch:

1. Tap Settings > iCloud. 
    
   • If you're using iOS 8 or later, tap Storage > Manage Storage.
    
   • If you're using an earlier version of iOS, tap Storage & Backup > Manage Storage.
2. Tap the name of your iOS device.
3. Under Backup Options, turn off any apps that you don't want to back up. When you're asked to confirm, choose Turn Off & Delete to turn off Backup for that app and remove all of its data from iCloud.

Manage your iCloud storage

If you are unable to disable which applications are backed up, please let me know if you are receiving any errors.

Cheers
