Windows Backup is a valuable tool for protecting your important files and system data. However, sometimes users encounter the “Server execution failed” error when trying to run a backup on Windows 11. This error can be frustrating, but it is usually fixable with a few simple steps.

In this guide, we will walk you through easy and detailed solutions to resolve the backup error. Each step is explained clearly, so even beginners can follow along without confusion.

By the end of this article, you will understand how to fix the issue and get your Windows Backup working smoothly again. Let’s start with some quick checks before diving into the solutions.

Follow the steps carefully, and your backups will be up and running in no time.

Quick Note: Prerequisites and Initial Checks

• Check your system updates: Make sure Windows 11 is fully updated. Sometimes, bugs causing errors are fixed in updates.
• Restart your computer: A simple restart can clear temporary glitches affecting backup services.
• Ensure enough disk space: Verify that the drive where backups are saved has sufficient free space.
• Run as administrator: Always run backup tools with administrator privileges to avoid permission issues.

Step 1: Restart Windows Backup Services

Windows Backup relies on several background services. If these services are stuck or not running properly, the “Server execution failed” error can appear. Restarting these services often fixes the problem.

1. Press Windows + R keys to open the Run dialog box.
2. Type services.msc and press Enter.
3. In the Services window, find the following services:
   • Windows Backup
   • Block Level Backup Engine Service
   • Volume Shadow Copy
4. Right-click each service one by one and select Restart.
5. If any of these services are not running, right-click and choose Start.

Why this matters: These services handle backup operations and snapshots. Restarting them refreshes their state and can clear errors.

Step 2: Run the System File Checker (SFC) Tool

Corrupted system files can cause backup failures. The System File Checker scans and repairs damaged files that Windows needs to run correctly.

1. Type cmd in the Windows search bar.
2. Right-click Command Prompt and select Run as administrator.
3. In the command prompt window, type the following command and press Enter:

   sfc /scannow

4. Wait for the scan to complete. It may take some time.
5. If any corrupted files are found, the tool will attempt to fix them automatically.
6. Restart your computer after the process finishes.

Why this matters: Fixing corrupted files ensures Windows Backup can access all necessary system components.

Step 3: Reset Windows Backup Settings

Sometimes, backup settings or configurations get corrupted. Resetting them can clear this issue without affecting your personal files.

1. Open Settings by pressing Windows + I.
2. Navigate to System > Storage > Advanced storage settings > Backup options.
3. Under the backup section, click Stop using this drive (if any drive is selected).
4. After stopping the backup, restart your computer.
5. Go back to the Backup options and set up your backup again.

Why this matters: Resetting clears any misconfigured backup targets or permissions that might cause the server error.

Step 4: Check Volume Shadow Copy Service Configuration

The Volume Shadow Copy Service (VSS) creates snapshots of your files during backup. If it is misconfigured, backups can fail.

1. Open the Services window again by typing services.msc in the Run dialog.
2. Locate Volume Shadow Copy.
3. Double-click it and set the Startup type to Automatic (Delayed Start).
4. Click Apply and then OK.
5. If the service is stopped, click Start.

Why this matters: Ensuring VSS runs automatically guarantees backups can create the required file snapshots.

Step 5: Use the Event Viewer to Identify Specific Errors

If the problem persists, checking the Windows Event Viewer can help pinpoint the exact cause.

1. Press Windows + X and choose Event Viewer.
2. Navigate to Windows Logs > Application.
3. Look for errors related to Windows Backup or Volume Shadow Copy around the time you tried to run the backup.
4. Click on the error to see detailed information.
5. Search online for any error codes or messages you find for more targeted solutions.

Why this matters: Event Viewer logs provide in-depth diagnostic information that can help identify less obvious issues.

Alternative Solutions and Advanced Options

If the above steps do not resolve the problem, consider these additional approaches:

• Create a new user account: Sometimes user profile corruption causes backup errors. Creating a new Windows user and testing backup there can help.
• Use third-party backup software: As a workaround, tools like Macrium Reflect or Acronis True Image can provide reliable backups.
• Perform a system restore: If the error started recently, restoring Windows to an earlier point can fix system faults.
