In the nbu admin. guide, the format for the bpduplicate command has an option
"-mpx" that allows for the duping
of multiplexed backups.  One of the vault parameters is duplicate_command.  This
allows you to specify the command to use to duplicate backups.  It is set to a
default of <netbackup dir>/bin/admincmd/bpduplicate -v.  My question is,
can you also specify the -mpx in this entry in the parameter file, i.e
duplicate_command <netbackup dir>/bin/admincmd/bpduplicate -v -mpx ???
