Let’s get started with some quick checks before moving on to detailed fixes.

Quick Note: Prerequisites and Initial Checks

  • Check Available Disk Space: Ensure that the drive you want to back up to has enough free space for the system image. Lack of space is a common cause of backup errors.
  • Verify Backup Destination: The backup location must be a local drive or an external drive properly connected and recognized by Windows.
  • Run Windows Updates: Make sure your Windows 8.1 system is up to date, as some fixes and improvements come through updates.
  • Restart Your Computer: Sometimes, a simple restart can clear temporary glitches causing the error.

Step 1: Run the Backup Troubleshooter

Windows 8.1 includes a built-in troubleshooter that can detect and fix common backup problems. This is a good first step because it automatically checks for issues and suggests fixes.

  1. Press Windows + W keys to open the Search charm.
  2. Type “Troubleshooting” and select the Troubleshooting settings from the results.
  3. Under the “System and Security” section, click on “File History” or “Backup and Restore”.
  4. Follow the on-screen instructions to run the troubleshooter and apply recommended fixes.

Running this tool helps identify if there are any misconfigurations or permissions issues causing the error.

Step 2: Check and Repair Disk Errors

Disk errors can interrupt the backup process and cause error 0x80780119. Running a disk check can fix corrupted files or bad sectors.

  1. Open Command Prompt as Administrator. To do this, press Windows + X and select Command Prompt (Admin).
  2. Type the following command and press Enter:
chkdsk C: /f /r

Replace C: with the drive letter where Windows is installed if different.

You will be prompted to schedule the disk check on the next restart. Type Y and press Enter.

Restart your computer. The disk check will run before Windows loads and repair any found issues.

Step 3: Ensure the System Reserved Partition is Healthy

The System Reserved Partition holds important boot files and recovery data. If this partition is too small or corrupted, backups may fail.

To check the status of this partition:

  1. Press Windows + X and select Disk Management.
  2. Look for a small partition (usually 100-350 MB) labeled “System Reserved.”
  3. Right-click it and select Properties.
  4. Under the Tools tab, click Check to scan for errors.

If the partition is missing or severely damaged, advanced repair steps may be needed, such as using third-party partition tools or reinstalling Windows.

Step 4: Disable Third-Party Security Software Temporarily

Sometimes, antivirus or firewall programs interfere with backup operations. Temporarily disabling them can help determine if they are the cause.

  1. Locate your antivirus icon in the system tray (bottom-right corner).
  2. Right-click the icon and choose Disable or Pause protection.
  3. Try running the backup again.

If the backup works after disabling security software, consider adding an exception for the backup program or switching to a less restrictive security solution.

Step 5: Use Command Line to Create a Backup

If the usual backup interface fails, you can create a system image using the command line. This method bypasses some issues in the graphical user interface.

  1. Open Command Prompt as Administrator.
  2. Type the following command to create a system image backup:
wbAdmin start backup -backupTarget:D: -include:C: -allCritical -quiet

Make sure to replace D: with your backup destination drive letter and C: with the drive containing Windows.

This command creates a full backup of your system and critical volumes without prompts (-quiet flag).

Alternative Method: Use Third-Party Backup Software

If Windows Backup continues to give you trouble, consider using trusted third-party backup tools. Programs like Macrium Reflect or EaseUS Todo Backup offer user-friendly interfaces and more flexible backup options.

These tools often handle disk issues better and provide better error reporting, which helps avoid error 0x80780119.
