   Arguments that specify the BACKUP operation to be performed.
   The argument-buffer argument is the address of a variable-length
   array of one or more Backup API option structures that define
   the attributes of the requested BACKUP operation. The variable-
   length array is terminated by an option structure of 16 bytes
   that contains all zeros.

                                  NOTE

      The length of the terminating option structure is 2
      longwords (16 bytes). The first longword identifies the
      option structure and has a value of 0. It is recommended
      that the second longword contain a value of 0.

   For more information about the Backup API option structures,
   refer to the OpenVMS Utility Routines Manual.
