From your picture posted I see that your device is not backing up. You need to buy more iCloud storage to back up your device,
iCloud backup doesn’t include information that is synced and stored in iCloud, like Contacts, Calendars, Bookmarks, Mail, Notes, Voice Memos, Messages*, shared photos, iCloud Photos*, Health data, call history, and files you store in iCloud Drive.
*-If you had turned on Messages in iCloud & iCloud Photos, your content is automatically stored in iCloud and is available on all devices that use the same Apple ID
