iCloud storage vs the hardware storage

Why do I need two locations to store the same files?

Imagine that someone stole your computer.

You should always have a backup.

You don't have to use iCloud and you can control exactly what it is used for. Visit your System Preferences. It's your call.

BTW, the main purpose of iCloud is to sync our data across all your devices. If you're not using iPhones and/or iPads in addition to your MacBook, the need for iCloud diminishes substantially.

Your backup strategy should be multiple media types in multiple places. A Time Machine backup to an external drive would be and should be part of your strategy. It would make sure you have the data you need.

Think "Backing up is not just for truck drivers." when you do something important. It will help you keep a strategy to secure your data.

You should move them from the iCloud Drive folder before turning it off.

This makes a copy on your actual hard drive vs. iCloud's virtual hard drive.
