What is UUID of IVssBackupComponentsEx4?

I've looked all through MSDN site and did not find anything, also this documentation is not so good about VSS related components.

Regards.

Solution

  • Search the Windows SDK include directory for these kind of COM interface names. You'll need at least version 8.0 since this is an interface that was added in Windows Server 2012.

    From the C:\Program Files (x86)\Windows Kits\8.1\Include\um\vsbackup.h file in my machine:

    const IID IID_IVssBackupComponentsEx4       = // f434c2fd-b553-4961-a9f9-a8e90b673e53
                    {
                    0xf434c2fd,
                    0xb553,
                    0x4961,
                    { 0xa9, 0xf9, 0xa8, 0xe9, 0x0b, 0x67, 0x3e, 0x53 }
                    };

    With the additional note that you shouldn't hard-code these IIDs but use the __uuidof keyword in your code. And that tagging the question with [visual-sourcesafe] is rather odd, this is a Volume Shadow Copy interface.
