As Ryan says, "a database export isn't considered a backup". But if you use RAC, most of the time a data pump job leaves a few lines in alert.log related to adding and, at the end, deleting a service named like 'SYS$SYS.KUPC$C_1_20130822161301*'. This may be captured in dba_hist_service_name. It's not reliable and doesn't work on single node databases. Finding SQLs in dba_hist_sql* and v$active_session_history for SQL text like '%sys.kup%' may be more reliable. Yong Huang -- //www.freelists.org/webpage/oracle-l
