Volume Shadow Copy Service (VSS) documentation updates

This is a summary of recent revisions to the VSS documentation on MSDN.


1.       In “Definition of Components by Writers” (http://msdn2.microsoft.com/en-us/library/aa381594.aspx),the “Adding Files to a Component” section has been expanded to include examples.

2.       In the VSS_DIFF_VOLUME_PROP reference page (http://msdn2.microsoft.com/en-us/library/aa384684.aspx), the descriptions of the m_llVolumeFreeSpace and m_llVolumeTotalSpace members now explicitly state that the amount of space is given in bytes.

3.       The following topics have been corrected to say that the method can return VSS_S_ASYNC_CANCELLED, not VSS_S_SYNC_CANCELLED:

a.       IVssSoftwareSnapshotProvider::QueryRevertStatus: http://msdn2.microsoft.com/en-us/library/aa819455.aspx
