  2. Error code 0x81000031 on using Windows Backup on Windows 10.

    Original Title: I cannot backup my Windows 10 computer using Windows Backup—error code 0x81000031

    Microsoft support could not fix the problem, but offered to let me try their paid ($99 per incident) support without guarantee that could cure it either.

    Windows backup failed - Error code 0x81000031 in Windows 10

    Hi,

    Thank you for contacting Microsoft Community. I understand that you have an issue with Windows Backup and receive error code
    0x81000031. I will surely help you to fix this issue.

    To understand the issue better, I would need more information from your end.

    • Do you have Windows BitLocker Drive Encryption on the system drive?
    • Do you have a custom library that is located on a removable drive or on a network drive?
    • What all troubleshooting steps did you tried to resolve the issue?
    This issue could have occurred due to these reasons:


    • Volume shadow copy Service is not started.

    • Conflict between antivirus software.
    Method 1:

    I suggest you to make sure “Volume shadow copy Service” is enabled.

    Follow these steps:

    a. Press “Windows key + R” from the keyboard.

    b. Type “services.msc” without quotes in the “Run” Window and hit
    Enter.

    c. Search for “Volume shadow copy" service.

    d. Right click on it and select “Start” option.

    e. Close the “Services” Window.

    f. Check if the issue persists or not.

    Method 2:

    If the issue persists, I suggest you to disable Antivirus software and check if it helps.

    Warning:

    1) Please make sure to re-enable Antivirus software after troubleshooting steps.

    2) Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable or uninstall your antivirus software. If you have to temporarily disable or uninstall it to install
    other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled or uninstalled, your computer is vulnerable to attacks.

    Hope this information helps. Reply to the post with updated status of the issue so that we can assist you further.

    can't resolve backup error code 0x81000031

    Windows backup failed - Error code 0x81000031 in Windows 10

    Bit-blocker is ON.

    Shadow Copy is RUNNING.

    Not sure what constitutes a "Custom Library". I have some important software on one 500gb external drive. (Quicken)

    I have tried backup with Antivirus OFF.

    Have formatted the backup destination drive (external 2tb) twice.

    Still get:

    "Windows backup failed while determining libraries location of one of the users included in the backup.

    Details: The device is not ready. Error code 0x81000031"

    Whew!
