BREAK [ READWRITE ] [ NOREVERTID ] 

        BREAK is relevant only for hardware shadow copies after import.
        The shadow copy disk provided by the hardware provider is disassociated
        from VSS as a normal volume in the operating system.

        It can then be accessed using a drive letter (if assigned), volume name or other means.
        This access is to the volume without any record of that volume ever being a shadow copy.
        It is the responsibility of the hardware to maintain this abstraction.

        READWRITE               Makes the volume read/write after break, otherwise it will be read-only.
        NOREVERTID              Prevents any identifier revert of the shadow copy disk/s.
                                Otherwise, all disk identifiers will be reverted.

        Example: BREAK READWRITE NOREVERTID %%shadowSetID%%
