Hi,

I agree it's best to continue features that work fine for most users. I'm here to lend a hand with using the automatic backup in QuickBooks Desktop.

Can you check if the option is also missing in the other company files? This way, we can determine the best resolution to get you back on track.

In the meantime, you can perform some troubleshooting steps to isolate and resolve the issue. I recommend running our repair tools for QuickBooks Desktop to fix unusual changes on your end.

Let's run the Quick Fix my Program from the QuickBooks Tools Hub. It helps fix common errors and missing options in the program.

Here's how:

1. Close QuickBooks.
2. Download the most recent version (1.6.0.3) of the QuickBooks Tool Hub. 
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
6. In the QuickBooks Tool Hub, select Program Problems
7. Select Quick Fix my Program.
8. Start QuickBooks Desktop and open your data file.

Problems during the QuickBooks install could cause problems when you try to use it. Run the QuickBooks Install Diagnostic Tool to fix common install issues.

Please follow these steps:

1. Open the QuickBooks Tool Hub, then select Installation Issues.
2. Select QuickBooks Install Diagnostic Tool. Let the tool run. It can take up to 20 minutes.
3. When the tool finishes, restart your computer and start QuickBooks Desktop, then open your data file.
4. Update your QuickBooks to the latest release.

After following the suggestions above, attempt to activate the automatic backup again. You should be able to access the option.

Aside from the scheduled backups, you can back up company files manually anytime. I've attached an article you can use to learn more about this method in QuickBooks: Back up your QuickBooks Desktop company file.
