Hi there, cdk19501.

Thanks for getting back to us. I'm here to help fix the issue you're having with Intuit Data Protect backup.

We can perform some troubleshooting steps to ensure you can successfully backup your company file using Intuit Data Protect. Let's start by checking if QBDT file is open via network drive. Intuit Data Protect will not be able to backup the file if it is open.

Here's how:

1. Close the QuickBooks company file.
2. Right-click the Intuit Data Protect icon in the system tray (next to the system clock), and choose Open Intuit Data Protect.
3. Select Back up now.

If the same thing happens, verify if the BuEngHost.exe is running as the System user and not the local user. Here's how:

1. Right-click on your Taskbar and select Start Task Manager.
2. Locate the process IBuEngHost.exe and look at the user listed in the User Name column. You may need to select 'Show processes from all users' in order to see IbuEngHost.exe. Note: If the users showing is anything other than System, IDP will not be able to back up opened files.
3. To correct this, verify QBIDPService.exe is started and reboot your system.

• To check if QBIDPService.exe is running open the Services Console from the Windows run line by typing in Services.msc and hitting Enter.
• QBIDPService.exe

If the results are still the same, check out this article for proceed to Solution 3 for more troubleshooting steps: Intuit Data Protect backup incomplete: Files did not backup because they were open or not reachable.

I'm also adding this article for the detailed steps on how to fix issues when you can’t back up your QBDT data file with Intuit Data Protect: Unable to back up with Intuit Data Protect.
