How to Fix Intuit (QuickBooks) Data Protect Not Working or Stopped Working?

QuickBooks Data Protect (QBDP) is a cloud backup service from Intuit that securely saves QuickBooks files and other important business data. The error “QuickBooks Data Protect Not Working or Stopped Working” appears when the backup process fails to start or complete. Common causes include outdated QuickBooks software, damaged Data Protect files, Windows compatibility issues, low storage space, or blocked connections caused by security programs or firewalls. Poor internet connections and server issues from Intuit can also interrupt backups. 

To fix the error, update Windows, .NET Framework, and QuickBooks to the latest versions. Ensure the system has an active subscription or payroll service. Run QuickBooks as an administrator, check Data Protect settings, and update or reinstall the backup tool. Also, review firewall rules, antivirus settings, and reset Internet Explorer if required. To avoid future issues, perform regular backups, monitor storage space, and allow QuickBooks services through all security software.

Method 1: Fix Intuit Data Protect Blocked by Firewall

Intuit Data Protect may stop working when Windows Firewall blocks its connection to the internet. This often happens because of incorrect firewall settings. Follow these steps to allow access:

1. Press Windows + R, type firewall.cpl, press Enter.
2. In the left panel, click Allow an app through Windows Firewall.
3. Select Allow another app, then go to this folder:
   C:\Program Files (x86)\Common Files\Intuit\Data Protect
4. Select QBIDPService.exe, click Open, then click Network Types.
5. Add QBIDPService.exe, select Private, click Add.
6. Repeat for:
   • IntuitDataProtect.exe
   • IBUenghost.exe

This process updates the firewall to let Intuit Data Protect work without errors.

Method 2: Install the Latest Version of Intuit Data Protect (IDP)

Installing the latest version of IDP helps fix known issues and ensures reliable backup performance. Follow these steps to complete the update:

Step 1: Update via QuickBooks

1. Open the Help menu and select Update QuickBooks.
2. Go to the Update Now tab.
3. Check the box for Data Protect.
4. Click Get Updates.

Step 2: Update Intuit Data Protect

1. Click the up arrow (^) in the system tray.
2. Right-click the Intuit Data Protect icon.
3. Select About Intuit Data Protect, then click Update.

Step 3: Finish Update

1. Click OK when the update finishes.

Method 3: Check if IBuEngHost.exe is Running Under the System User

IBuEngHost.exe must run under the System user for Intuit Data Protect to function correctly. Follow these steps to check:

1. Press Ctrl + Alt + Delete and open Task Manager.
2. Go to the Processes tab.
3. Find the process named IBuEngHost.exe.
4. Check the User Name column.

When the process is not running under System, uninstall Intuit Data Protect and reinstall it using a Windows administrator account.

Method 4: Add Intuit Sites as Trusted in Internet Explorer

After allowing key files through the firewall, add Intuit-related websites as trusted sites to avoid connection issues.

1. Click the Windows icon and search for Internet Options.
2. Go to the Security tab and click Trusted Sites.
3. Click Sites and add these URLs one by one:
   • https://intuitdataprotect.com
   • https://backup.com
   • https://intuit.com
   • https://intuit.net
   • https://quickbooks.com
   • https://workplace.intuit.com
   • https://emerald.backup.com

Important: Uncheck Require server verification (https:) for all sites in this zone before clicking Close. Keeping it checked can trigger the “QuickBooks has detected a problem with your data file” error.

• Click Close, then OK to save changes.

Method 5: Check If the Drive Uses the NTFS File System

Intuit Data Protect requires the drive to use the NTFS format for reliable backup. Use the steps below to verify:

1. Open My Computer or This PC.
2. Right-click the C Drive.
3. Select Properties.
4. Check if NTFS is listed as the file system.

Key Points:

• Close the QuickBooks company file during backup if it’s on a different computer than Intuit Data Protect.
• When backing up from a network location, use a mapped drive instead of a UNC path (e.g., \\server\folder).
• Avoid UNC paths to prevent backup errors.

Method 6: Add Windows Firewall Ports for QuickBooks and IDP

Blocked firewall ports can prevent QuickBooks and Intuit Data Protect (IDP) from working properly. Add the required ports to Windows Firewall to fix backup errors.

1. Open the Start menu, type Control Panel, and press Enter.
2. Go to System and Security > Windows Firewall.
3. Click Advanced Settings on the left.
4. In the left panel, select Inbound Rules.
5. On the right side, click New Rule.
6. Choose Port, then click Next.
7. Under Protocol and Ports:
   • Select TCP.
   • Enter port 80 for incoming.
   • Enter ports 443 and 16841 for outgoing.
8. Click Next, then choose Allow the connection.
9. In the Profile section, check Domain, Private, and Public.
10. Click Next and finish the setup.

Repeat the same steps under Outbound Rules.

Note: Ports 80 and 443 are required for internet access. If your browser opens secure websites, IDP should connect without issues.

Check if the backup error is resolved after these changes.

Method 7: Repair the Microsoft .NET Framework

Intuit Data Protect (IDP) relies on the Microsoft .NET Framework to run properly. Errors in this framework can affect backup functions. Follow these steps to repair it:

1. Close all open programs.
2. Click the Start menu and search for Control Panel.
3. Open Control Panel and go to Programs and Features.
4. Click Uninstall a Program.
5. On the left, select Turn Windows features on or off.
6. Find .NET Framework in the list and manage its settings:
   • Uncheck it, click OK, and restart the computer.
   • Then go back, check it again, click OK, and restart once more.

This process repairs the .NET Framework and helps restore proper IDP functionality.
