makey,
The screenshot's helpful, but it shows your Apple ID. Anytime you are sharing screenshots, and such, make sure your personal info is blocked so it's not seen. This is a public forum, so all information shared is viewable.
Let's get back to restoring from a backup. We have a few questions that will help us understand a little more about what's happening.
1 - Do you know the size of the backup? Looking at what you shared, you have 5GB of storage available.
2 - How old is the backup?
3 - What is the iOS version installed on the iPhone that is being used to restore the backup on?
This will show you how you can Locate backups of your iPhone, iPad, and iPod touch that might be available:
"Find and manage backups stored in iCloud
If you use iCloud Backup, you won't find a list of your backups on iCloud.com. Here's how to find your iCloud backups on your iOS or iPadOS device, Mac, or PC.
On your iPhone, iPad, or iPod touch:
- Go to Settings > [your name] > iCloud.
- Tap Manage Account Storage, then tap Backups.
- Tap a backup to see more details about it, choose which information to back up, or delete the backup.
You can choose which content to back up only from the Settings menu of the device that stores that content. For example, while you can view your iPad backup from your iPhone, you can choose which iPad content to back up only from the Settings menu of your iPad."
If you don't see the backup in question, depending on how old it is, it may no longer be available. Let us know what you find.
We look forward to hearing back from you!
