SQL查询oracle数据库最近备份情况

需求，查询RMAN备份情况，通过视图进行查询

SQL> select sid,OUTPUT_DEVICE_TYPE,OPERATION,STATUS,object_type,mbytes_processed,START_TIME,END_TIME,round(INPUT_BYTES/1024/1024/1024,2) input_g,
  2  round(OUTPUT_BYTES/1024/1024/1024,2) output_g from v$RMAN_STATUS where  start_time>sysdate-30 order by 7;

       SID OUTPUT_DEVICE_TYP OPERATION                                     STATUS                    OBJECT_TYPE   MBYTES_PROCESSED START_TIME          END_TIME               INPUT_G   OUTPUT_G

--需要注意，数据库RMAN BACKUP DATABASE 是DB FULL全备类型，但是需要注意，客户是0级全备，备份类型也是DB INCR
