Hello there, @dtocswcd.

I'm here to provide information and steps to help you successfully back up your company file in QuickBooks Desktop (QBDT).

First off, consider downloading and installing QuickBooks Tool Hub. Then, follow the steps below:

1. Close QuickBooks.
2. Download the most recent version (1.6.0.3) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be on the bottom.
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.

After that, proceed to Steps 2 and 3 in this article: Fix company file and network issues with QuickBooks File Doctor.

If the issue persists, I suggest reverifying and rebuilding your data. If it doesn't fix the issue, I recommend reaching out to our Customer support so they can provide details and help you sort it out.

Here's how to contact them:

1. Select QuickBooks Desktop Help from the Help menu.
2. Click Contact Us.
3. Type in a short description of your concern, then Continue.
4. Choose a way to connect with support.

Moreover, I'm adding this helpful article as your reference on how to handle import issues and common issues in your company file: Fix Web Connect import errors.
