  • Hi,

    Thanks for your question. As per my understanding, the issue you are experiencing is that you failed to restore the server and you see the error message. Please correct me if there’s any misunderstanding.

    According to the error message, the operation failed because the backup catalog is corrupted. You could try to run the command wbadmin.exe to restore the catalog. Below are the steps

    1. Select the start button

    2. Type cmd

    3. Right click the Command Prompt and select Run as administrator

    4. Run the command wbadmin restore catalog

    For exampleto restore a catalog from a backup stored on disk d:, type:

    wbadmin restore catalog -backupTarget:d

    You may refer to the link below for more details

  • Hello,

    Thanks for reply.

    i tried webadmin way from cmd but it give me the same error .

    i was infected by Yakuza ransomeware and there is a doubt that the vhdx files in the windows image backup are corrupted as it can not be even mounted.

    i do not know if there is a solution for that.

    Really appreciate your cooperation.

  • Hi Moh Lotfy,

    Sorry for hearing that. If the vhdx cannot even be mounted, the vhdx could be corrupted and we could do nothing for that from Windows side. It could be the MBR or GPT of the vhdx disk corrupted by the ransomeware. One way you could try is disk recovery. There're some 3rd party tools can do that but there's always a risk of failure, so backup your vhdx before you try.
