"deleted"                               In backup summary statistics, as in
                                        "Total number of objects deleted:".
                                        Refers to the number of files expired
                                        because not found (or excluded) in the
                                        backup operation.  Those files will be
                                        flagged in the body of the report with
                                        "Expiring-->".
