If you're tired of having to clean up your storage and get rid of old, useless, data, you can turn off the automatic backups. We have a full tutorial on the subject here, but it's really easy. 1. All you need to do is click on the Apple icon and click "System Preferences." 2. Locate "Time Machine" and double-click to open it. 3. Then, you can uncheck the option for "Automatic Backup" on the left side.
