How to Fix Windows Backup 0x8078012D Error?

Have you ever used Windows Backup on an external hard drive and received the error code 0x8078012D? If so, you need not be concerned because you are not the only one who has this issue.

The input-output device can be the primary culprit of this problem. Try to fix the issue listed below if you are unable to utilise the previously produced system backup on your PC or it is resulting in error code 0x8078012D. We advise you to update Windows before continuing.

Restart your PC in Safe Mode

If the following adjustments did not resolve the issue, there could be a particular programme that is to blame. To troubleshoot this, select Clean Boot PC in Windows 10 to start your computer in clean boot mode and identify whether a particular programme is to blame.

Run CHKDSK scan on your Drive

If the following solution does not resolve the issue, you should look into if the issue is connected to the HDD/SSD storage. A CHKDSK (Check Disk) scan enables the detection of faulty logical sectors and their replacement.

To access the WinX menu, use the Windows key + X.

To start PowerShell with administrator rights, select Windows PowerShell (Admin) from the menu. If a UAC prompt appears, select Yes to proceed.

run chkdsk to fix windows backup 0x8078012d error

Enter the settings you wish to use for the scan after typing chkdsk X: in the PowerShell window, where X is the drive letter for the partition of your system hard disc that you want to check.

Running a scan without the specified parameters will simply scan the currently chosen drive and will not correct any issues.

Use the command on CMD:

chkdsk C: /f

Or

chkdsk D: /f /x

You can use the following parameters:

/f - Tells CHKDSK to fix any and all errors that it finds
/r - Tells CHKDSK to locate bad sectors on the drive and try to recover any and all readable information from them
/x - Tells CHKDSK to forcefully dismount the selected drive before scanning it

Watch for the CHKDSK utility to complete its task. You may keep track of the utility’s advancement at the time of the scan.

While Windows is running on a disc, the CHKDSK tool cannot scan that partition. In this situation, you will be prompted to decide whether you want the programme to run the scan the next time your machine wakes up.

Create a Windows Backup

To see the Run dialogue, press the Windows key and R. Enter services.msc in the Run box to access the Services interface. If User Account Control (UAC) asks you to authorise access, select Yes.

Search the list of services under Services on the right side until you locate an entry for Windows Backup.

To access the context menu, right-click Windows Backup and choose Properties.

windows backup service

Change the Startup type to Automatic in the Properties screen’s General tab, then click Start to restart the service if it has been halted.

Use the modifications. To see if the 0x8078012D problem code is fixed, restart the computer and carry out the same operation that caused it.

Remove any Third Party Software

It’s conceivable that a false positive is influencing the backup and causing the error if you’re using a third-party security suite or firewall. By turning off the security suite before launching Windows Backup, you may probably prevent the error code when generating a backup.

To disable real-time protection, right-click on the antivirus software’s tray icon and seek for the option.

If deactivating did not resolve the problem, go to the Programs and Features menu and remove the third-party security programme.

This approach shouldn’t be used if Windows Defender is installed because there is no proof that it interferes with the backup service.

Create New Backup in Clean Boot

Open “System Configuration” by selecting it in the Start Menu.

Click the Normal Startup option under the “General” menu.

Select Hide all Microsoft Services under the “Services” pane, then click Disable all.

Select “Apply” > “OK.”

create new backup service

Use the Windows Backup and Restore programme to now generate a backup.

Turn on Windows Backup Service

If the Windows Backup Service is turned off under the Windows Services, this issue could also arise. We advise you to open the Services app and verify if it is switched on or off in order to resolve this problem. If you discover it turned off, follow the instructions below to activate it.

start windows backup service
  • Type Services into the Start search box and hit Enter.
  • Scroll down to the Windows Backup service in the Services app.
  • It may be double-clicked to see the Properties window.
  • Set Manual Startup to the General tab.
  • Verify that the service is active under Service status. The Start button should be clicked if it is Stopped.
  • Click Apply > OK to keep the changes in place.

Close the Services programme after completing the previous instructions, restart your computer, and see whether it works.

Try SFC and DISM scans

The two built-in utility System File Checker (SFC) and Deployment Image Servicing and Management (DISM) are capable of resolving the majority of corruption problems that might result in the 0x8078012D error using Windows Backup.

While DISM employs a feature of Windows Update to replace corrupted instances of windows files downloaded from the internet, SFC is a local programme that doesn’t need an active internet connection since it uses the locally stored cache to replace corrupted system files.

use sfc and dism command

Open Command Prompt in Administration Mode.

Type sfc /scannow

The next 10-15 minutes will pass as this utility searches for and corrects damaged or missing files and directories.

After this is finished, make careful to inspect the system image for any file corruption. Run the code listed below on the active PowerShell or Command Prompt to do this.

DISM /Online /Cleanup-Image /RestoreHealth

It will also take DISM 10 to 15 minutes to locate and fix any issues with the system image. Wait patiently, and once it’s finished, see whether you can now generate a fresh backup without encountering the 0x8078012D issue or any other problems.

Delete Shark007 Codec

A few users claimed that removing the Shark007 codec from their PCs resolved this problem. This codec has a history of interfering with system backups and returning various error codes, notably 0x8078012D. Whether you do use this tool, stop using it and see if the issue is solved.

  • Start by opening Control Panel.
  • Locate “View by” and choose Large icons from the drop-down menu.
  • By doing this, the Control panel’s programmes will all be visible.
  • Look for the Shark007 tool in Programs and Features.
  • If it’s there, right-click it and choose “uninstall.”
  • Press Uninstall one again if a confirmation box has appeared.

After the software has been properly removed, restart your computer. Now see if your machine still supports the backup you previously generated.

Check User Profile

Even after deleting the prior backup, try creating a new account and going through the backup procedure again if you are unable to save the freshly produced backup:

  • Select Start.
  • Press Control Panel.
  • Select Family Safety and User Accounts.
  • Tap User Accounts.
  • To manage another account, click.
  • To open a brand-new account, click Create a New Account.
  • Switch off your computer.

You must log out of your current account and log in with the newly established account after this new account has been created. Restart Windows Backup and check to see whether the 0x8078012D error still occurs.

Scan for any Corrupted or Missing Files

You can use Microsoft Safety Scanner to determine whether certain corrupt files are to blame for the error:

microsoft safety scanner
  • Visit: Microsoft Safety Scanner Download
  • Click on the download button.
  • Install Safety Scanner by according to the installation guidelines.
  • Start the Microsoft Safety Scanner programme.
  • Choose Scan Type.
  • Tap Full Scan.
  • Choose Next.

The infected files will be removed if any virus/corrupted or missing file is found.

What to do next?

You must create a fresh system backup on your computer once you successfully fix the backup problem on your Windows 11 or Windows 10 computer. Any backup error code that appears on your computer in the near future will be eliminated thanks to this.
