I finally have this issue resolved. Oracle Streams had been setup for this database, but was disabled. Therefore, Oracle apparently thought it needed to keep the archivelogs around. I ran the following command as SYS: exec dbms_streams_adm.remove_streams_configuration() ; "report obsolete" now lists the archivelogs that have been backed twice. Thank you for all of the responses.
