Windows Backup Not Working? Try This Fix

Genuine backup tools in Windows have a reputation for being unreliable and prone to errors, and that’s not without reason.

Some users can’t set up automatic backups, while others can’t even back up manually due to various errors. Even in many cases that are initially successful, backups become useless because you can’t restore anything from them.

Since there are many such scenarios, we have divided this article into two parts covering backup and restore errors for easy reading.

  • File system error
  • Conflict with old backup

  6. Run the following command:
    chkdsk C: /f /x /r
    DISM /Online /Cleanup-image /Restorehealth

    Sfc /scannow
    dism sfc

Use System Image Backup

  1. Open Control Panel and click Backup and Restore.
  2. Click Create system image from the left panel.
    create system image

  4. Apart from the system partition, select the additional items that you want to include in the backup.Backup system image
  5. Confirm the selection and press Start backup.

Fix Backup Restore Problem (Case 2)

When restoring from a backup, you may encounter error 0x80070003 if the reparse point directory is deleted. You can fix this error by recreating the missing directory. Here are the steps to do it:

  1. The error message should also indicate the path of the missing file. Navigate to this path and create the appropriate folder.a-file-cannot-recover
  2. Run the recovery wizard again and make sure you have activated that Restore files to their original subfolders choice. The error should be resolved now.

Users have also reported cases where they were only able to restore a portion of the backup content. This is likely because the backup was corrupted from the start or at some point afterward. Unfortunately, there’s not much you can do in such cases.

As we stated earlier, most native backup tools in Windows are unreliable. Our best recommendation is to create a system image or use a reputable third-party backup tool and save the created backup on an external drive. A third copy in the cloud would be ideal.
