Here are the steps to achieve that:

You can also fix your iPhone's backup stuck issue by restarting your iPhone. To achieve that, do the following:

Usually, Whatsapp rolls out its updates on iOS. Failure of Whatsapp backup can be due to a recently buggy build that's installed on your gadget.
To update your Whatsapp: Open Apple Store on your iPhone and go to the update section to download the latest Whatsapp.
Sometimes, your Wi-Fi may be poor or slow. So, test the internet speeds to ensure that it's working effectively. If the network is your home network, then you may restart it. You will also have to reset iPhone settings if the network is not good. Navigate to iPhone Settings > "General", scroll down, click "Reset", and click "Reset Network Settings".

If your Whatsapp backup is still not progressing, check the iCloud server status since it might be causing the issue. To check if iCloud/Google Drive servers are down, go to https://www.apple.com/support/systemstatus/, and check the iCloud server status.
If everything is marked green, know that the status of the iCloud server is normal, but if you find some parts labeled orange, then there are errors in the iCloud.

This method avoids all cloud-related issues, stores your data locally for higher security, and supports flexible access and restoration at any time.
