Q: Im trying to back up my icloud but it says its going to take 14 hours is this normal?

Hello GeorgiaChilvers,

Welcome to Apple Support Communities.

It depends on your specific circumstances as to what is "normal". See the following article:

Specifically:

My backup is taking a long time to finish.

Backing up and restoring takes time, especially if you have a lot of data or a slow connection. Depending on the size of your backup and the speed of your network, you may need more time than expected to complete the process. Using a reliable connection when backing up your device is highly recommended.

Regards,
