Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More Information

When the source file is large enough, the BaseCopyStream function tries to perform an Offload Copy process. However, when you try to copy a VSS backup from the local drive to a local directory, the Offload Read command fails. Then, the BaseCopyStream function tries to reset the file pointers on the handles to perform a normal copy. In this situation, the SetFilePointer call on the VSS file fails with the STATUS_MEDIA_WRITE_PROTECTED error because the volume is read-only.
