VMS Help  —  BACKUP  Qualifiers  /DENSITY
       /DENSITY=n

    Specifies the recording density of the output magnetic tape. Use
    a value that is supported by the magnetic tape drive.

    If you do not specify the /DENSITY qualifier, the default density
    is the current density of the magnetic tape drive. You must
    specify the output save-set qualifier /REWIND with /DENSITY.
