Hello funsizemars,
Please check out the following link, which outlines what iCloud backups include, and may be helpful: What does iCloud back up?
"Here’s what iCloud Backup includes
- App data
- Apple Watch backups1
- Device settings
- Home screen and app organization
- iMessage, text (SMS), and MMS messages2
- Photos and videos on your iPhone, iPad, and iPod touch2
- Purchase history from Apple services, like your music, movies, TV shows, apps, and books3
- Ringtones
- Visual Voicemail password (requires the SIM card that was in use during backup)
Your iPhone, iPad, and iPod touch backups only include information and settings stored on your device. They do not include information already stored in iCloud such as Contacts, Calendars, Bookmarks, Notes, Reminders, Voice Memos4, Messages in iCloud, iCloud Photos, and shared photos. Some information is not included in an iCloud backup but can be added to iCloud and shared across multiple devices like Mail, Health data, call history, and files you store in iCloud Drive.
1. If you use an Apple Watch with Family Setup, your Apple Watch isn't included in the backup of an iPhone, iPad, or iPod touch.
2. When you use Messages in iCloud or turn on iCloud Photos, your content is automatically stored in iCloud. That means that they're not included in your iCloud Backup.
3. Your iCloud Backup includes information about the content you buy, but not the content itself. When you restore from an iCloud backup, your purchased content is automatically redownloaded from the iTunes Store, App Store, or Books Store. Some types of content aren’t downloaded automatically in all countries or regions. Previous purchases might be unavailable if they've been refunded or aren't available in the store. Find out what you can redownload and buy in your country or region.
4. If you use iOS 11 or earlier, Voice Memos are included in iCloud Backup."

Thanks!
