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

       /LOG
       /NOLOG (default)

    Generates a log of the recovery operation. When you use the
    /LOG qualifier, the RMS Recovery Utility displays the number
    of records that were processed during the recovery operation,
    and the date and time of the last record that was processed
    (recovered).
