0X81000037 Windows 10 – Fixing Backup or Restore Errors

0x81000037, 0x80070001, and 0x80070003 are errors caused by Windows finding a “parse point” within a folder that you are trying to back up.

Microsoft mentions that “parse points” are the Windows equivalent of symbolic links in Linux. They allow you to “link” a folder to a different location on your hard drive, without having to move the folder.

The reason I get the error is because when Windows tries to “back up” the folder in question, it cannot find the file that is linked within it. This makes Windows think that the file does not exist, is inaccessible, or is corrupted.

The errors will generally appear with these messages:

0x81000037 – Windows backup failed when trying to read from snapshot on one of the volumes being backed up

0x80070001: (invalid function)

0x80070003

To fix them, you need to delete the scan points within the folders you are trying to back up.

Because

The main cause of the problem is that Windows does not recognize the location of a file.

The error can appear when using Windows Update, scheduling a restore point, or generally showing when you are using your system.

To fully understand the problem, you need to understand that each time you use a personal computer, all it does is process billions of lines of code, many of which are stored in “files” on your persistent storage device (either on the hard drive or SSD). .

On most operating systems, you can allow applications to load particular files by “linking” them to other locations on your hard drive.

For example, you may have a game file saved in your “Saved Games” folder, which you can include in your actual game folder via a “symbolic link”.

SymLink functionality is native to Linux and is used by Mac as well. Windows, being Windows, does not use “symbolic links”, but “parsing points”. The functionality is the same in both cases.

The errors you are experiencing are due to your system being unable to load particular files, due to their lack of physical presence on the drive. To fix this, you must correct the underlying errors that are causing the error to be displayed.

Solution

The way to fix the problem is to make sure that you can clean up any of the folders that may be causing problems with the “scan points”.

Microsoft offers 3 ways to solve the problem:

  • Scan point directly to a volume that uses FAT as its file system

  • The parse point is a “mounted volume” containing compressed files (EG zip files, etc.)

  • Parse the point directly to the “root” of another volume

To solve it, you need to follow the steps outlined below:

1. Remove all “mounted volumes” / “reparse points”

The first step is to make sure that you do not have any “mounted volumes” or “scan points” on your system.

This may sound complicated, but it is actually relatively simple:

  • On your keyboard, press the “Windows” + “R” keys

  • This will open the “Run” dialog – in it type “cmd” and press “Enter”

  • From the cmd prompt that appears, type “DIR / AL / S” and hit “Enter”

  • This should display a list of directories classified as “Reanalysis Points”

  • From the list, take the ones you think are corrupting the backup, find them in “File Explorer”

  • When you identify the folder, right click on the volume and check if it says “Mounted volume”

  • If so, delete it by holding the SHIFT key and pressing CLEAR

  • Once this is complete, restart your computer

After the reboot, you should be able to test what you were trying to do before.

If the error disappears, it means that the problem has been solved; otherwise, you will need to continue with the next steps.

2. Secure permissions

Then the other problem you may have is the system permissions. Permissions are used in computing to determine which users can (and cannot) manage various resources within the system, and are generally based on “user roles” (administrator, etc.).

To ensure that errors are not repeated, you may have issues regarding the way your user account can access particular files / settings.

To fix this problem, you need to be able to correct any permission issues your system may have:

  • Go to the folder (s) you are trying to backup / restore

  • Right click on the folder and select “Properties”

  • In the “Properties” dialog box, select “Security”.

  • Here, press “Edit”

  • In the window that appears, type “All” in the box and click “Check Names.”

  • If the text “All” is underlined, click “OK”

  • With “All” selected, click “Allow” for “Full Control” in the lower pane.

  • Click OK “

  • Try to backup / restore again

If this doesn’t work, be sure to repeat the process for any other folders you are trying to back up. While it shouldn’t be a problem for most users, it is likely to cause problems * if * your system is heavily used (permissions not working etc). Other problems are likely to be caused by some kind of “lock” on the folders, either by antivirus or perhaps by a virus infection in the system.

3. Clean virus / malware

Then your computer * may * have problems with virus / malware infections.

While this may not seem like a cause of a file system error, the problem lies in the way many newer viruses end up targeting underlying files / folders, to block user access OR make sure the infection has the ability to do their nefarious work.

The point is that if you are still experiencing the errors, it may be caused by a virus infection temporarily overwriting certain files / folders on your hard drive.

To fix this issue, you need to make sure you have adequate virus / malware protection:

  • Download MalwareBytes (free)

  • Save it and install it on your PC

  • Open the zip file and then run the software inside

  • When the software runs, set it to perform a full scan

  • After the scan is finished, reboot your system

Unlike viruses, “malware” (malicious software) often disguises itself as legitimate software applications and only causes problems * after * they gain access to your PC.

MalwareBytes is the only tool completely dedicated to removing malicious infections from Windows systems. If after performing the above steps and removing potential malware threats, Windows is still unable to perform a backup, you’d better seek the opinion of someone with more specific knowledge of your system. You can also disable any antivirus applications you have running as they could conflict with (crash) the backup process.

4. Run the “Troubleshooter” tools

If you are still experiencing the error, you should run one of the “troubleshooters” within Windows 10.

The troubleshooting systems within W10 are relatively effective and work as follows:

  • Click the “Start” button (lower left task bar)

  • Select the “gear” / “Settings” icon in the “Charms” menu on the left (just above the power button)

  • When the “Settings” screen loads, click “Update & Security”

  • In the menu on the left, select “Troubleshoot”.

  • From the list that appears, you should first click on “Windows Update” and then on any other that pertains to what you are trying to do.

  • A small applet will load – let it run and then let it clean up any problems it finds

  • Once completed, restart your PC

This will generally solve any of the core issues Windows 10 has that are preventing the likes of Windows Update from working. It’s not guaranteed to work, but it works for many common bugs that inhibit core W10 functionality.

5. Run SFC / DISM

Finally, if you are unsuccessful with the above, running the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) tools are a great way to ensure that the main Windows system is running smoothly. most effective way possible.

To do this, you need to follow the steps outlined here:

  • Press the “Windows” + “S” keys on your keyboard

  • Type “CMD” in the search box.

  • From the list that appears, right-click on the top list and select “Run as administrator”

  • When the CMD window loads, type “SFC / scannow” and hit “Enter”

  • After this completes, type “DISM / Online / Cleanup-Image / RestoreHealth” and hit “Enter”

  • Once this is complete, reboot your system

If the errors persist beyond these steps, it suggests a more specific problem with your particular system that an Internet article will not be able to resolve on its own.

Additional steps to resolve the error should involve someone who has specific access to your specific Windows system. To do this, there are a number of online services that can help, including SuperUser and Microsoft Answers. If you need more specific assistance, you may want to contact a dedicated technician, although that will involve paying someone.
