Window 7 backup fails with error code 0x8031004a RRS feed

  • Question

  • Attempting to backup up even a single folder containing a single file results in a Windows 7 Pro SP1 error

        BitLocker Drive Encryption cannot be used because critical
        BitLocker system lies are missing or corrupted. Use
        Windows Startup Repair to restore these filess to your
        computer.

        Backup tIne: 12/31/2015 12:36 PM
        Backup location: USB30FD (E:)
        Error code: Ox8031004A                             

    The folder to be backed up is in the C: root directory and is not in the Windows 7 Library.

    Creating and running a Windows Startup Repair Disk has no effect.

    How does one restore missing or corrupted BitLocker files in Windows 7 Pro SP1 so that a Windows backup can be made?

Answers

  • I would start by disabling bitlocker and running a system file check to find the state of the OS

    Please run a system file check (SFC) & DISM  if you are on win 8 or higher

  • Hi,

    We hope your issue has been resolved.

    If your issue still persists

    Try following these steps:

      • Connect the external hard disk drive to the computer. Make sure that the external hard disk drive is powered on.
      • Create a Windows 7 system repair disc. To do this, follow these steps:
        1. Click Start, and then type create a system repair disc in the Start Search box.
        2. In the Programs list, click Create a System Repair Disc.
        3. Follow the instructions on the screen to create the disc.

    Note You must have a CD or DVD burner to create a system repair disc.

    1. Start an elevated command prompt. To do this, follow these steps:
      1. Click Start, and then type command prompt in the Start Search box.
      2. In the Programs list, right-click Command Prompt, and then click Run as administrator.
    2. At the elevated command prompt, type the following command, and then press ENTER:

    C:\Windows\System32\REAgentC.exe /disable

    1. Disconnect the external hard disk drive.
    2. At the elevated command prompt, type the following command, and then press ENTER:

    C:\Windows\System32\REAgentC.exe /enable Note This operation might fail. In this case, use the Windows 7 system repair disc that you created in step 2 if you have to have access to recovery tools.

    1. Reconnect the external hard disk drive to the computer.
    2. Start the Backup and Restore Wizard to back up your files and data to the external hard disk drive.
