How to Fix Error 0x8078011e on Windows 11: Step-by-Step Solutions

Error code 0x8078011e can appear on Windows 11 when you try to create a system image backup or perform certain backup operations. This error usually indicates that the backup process has encountered a problem and cannot complete successfully.

Fixing this error is important to ensure your system data is safely backed up and protected. Fortunately, the solutions are straightforward and can be done without advanced technical knowledge.

In this article, you will find step-by-step instructions explained in the simplest way possible. Following these will help you resolve the error and get your backup running smoothly again.

Let’s dive into the solutions, starting from the easiest checks to more detailed fixes.

Quick Note: Prerequisites and Basic Checks

Before you begin troubleshooting, make sure of the following:

  • Your Windows 11 system is up to date. Updates often fix bugs related to backup tools.
  • You have enough free disk space on the drive where the backup will be saved.
  • The external drive or location used for backup is properly connected and accessible.
  • You have administrative rights on your PC, which are needed to perform backups and system changes.

Checking these basics can save time and prevent unnecessary steps.

Step 1: Restart Your Computer

Sometimes, a simple restart can clear temporary glitches that cause backup errors.

To restart:

  1. Click the Start button.
  2. Select the Power icon.
  3. Choose Restart.

After your PC restarts, try to run the backup again to see if the error persists.

Step 2: Run the Windows Backup Troubleshooter

Windows has a built-in troubleshooter that can automatically find and fix common backup problems.

To use it:

  1. Press Windows + I to open Settings.
  2. Go to System > Troubleshoot.
  3. Click on Other troubleshooters.
  4. Find Backup in the list and click Run.
  5. Follow the on-screen instructions.

This tool checks backup-related settings and attempts to repair issues automatically.

Step 3: Check and Restart the Volume Shadow Copy Service

The Volume Shadow Copy Service (VSS) is essential for creating backups. If this service is stopped or malfunctioning, backups can fail with errors like 0x8078011e.

To check and restart VSS:

  1. Press Windows + R to open the Run dialog.
  2. Type services.msc and press Enter.
  3. In the Services window, scroll down to find Volume Shadow Copy.
  4. Right-click it and select Properties.
  5. Make sure the Startup type is set to Manual or Automatic.
  6. If the service is not running, click Start.
  7. Click OK to save changes.

After restarting the service, attempt the backup again.

Step 4: Run System File Checker (SFC) and DISM to Fix Corrupted Files

Corrupted system files can cause backup errors. Windows provides tools to scan and repair these files.

To run these tools:

  1. Click the Start button, type cmd.
  2. Right-click Command Prompt and choose Run as administrator.
  3. In the black command window, type the following and press Enter:
    sfc /scannow
  4. Wait for the scan to complete. It may take some time.
  5. After that, type the following commands one by one, pressing Enter after each:
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth
  6. Once done, restart your computer and try the backup again.

These tools help repair corrupted files that may cause backup failures.

Step 5: Clear the Windows Backup Catalog

A corrupted backup catalog can prevent new backups from completing. Clearing it can fix the issue.

To clear the catalog:

  1. Open Command Prompt as administrator (see Step 4).
  2. Type the following command and press Enter:
    wbadmin delete catalog
  3. Confirm the action if prompted.

This will delete the backup catalog, forcing Windows to create a fresh one on the next backup.

Alternative Method: Use Third-Party Backup Software

If Windows Backup continues to give error 0x8078011e despite troubleshooting, you can try third-party backup tools. Programs like Macrium Reflect, Acronis True Image, or EaseUS Todo Backup offer reliable alternatives and often provide more features.

These tools can create system images and backups without relying on Windows Backup services, potentially avoiding the error.
