VMS Help BACKUP Command, Qualifiers, /BRIEF  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Command Qualifier

    Causes the /LIST qualifier to display the file specification,
    size (in blocks), and creation date for each file in the save
    set. The /BRIEF qualifier is valid only with the /LIST qualifier
    and is the default format for BACKUP listings.
