Backup time

 You can find your backup time with the following query

SELECT * FROM (SELECT END.dt, 'Incremental' BACKUP, STAR.TIME started, END.TIME END,  

DECODE(TRUNC(END.TIME - star.TIME), 0, NULL, TRUNC(END.TIME - star.TIME) || ' Days' || ' + ') ||

TO_CHAR(TO_DATE(TRUNC(MOD(END.TIME - star.TIME,1) * 86400), 'SSSSS'), 'HH24:MI:SS') TIME

FROM 

(SELECT TRUNC(start_time) dt , MAX(COMPLETION_TIME) TIME FROM V$BACKUP_SET WHERE BACKUP_TYPE='I'

GROUP BY TRUNC(start_time)) END, 

(SELECT TRUNC(start_time) dt, MIN(START_TIME) TIME FROM V$BACKUP_SET WHERE BACKUP_TYPE='I'

GROUP BY TRUNC(start_time)) STAR

WHERE END.dt = STAR.dt 

UNION ALL

SELECT END.dt, 'Full Database' BACKUP, STAR.TIME started, END.TIME END,  

DECODE(TRUNC(END.TIME - star.TIME), 0, NULL, TRUNC(END.TIME - star.TIME) || ' Days' || ' + ') ||

TO_CHAR(TO_DATE(TRUNC(MOD(END.TIME - star.TIME,1) * 86400), 'SSSSS'), 'HH24:MI:SS') TIME

FROM 

(SELECT TRUNC(start_time) dt , MAX(COMPLETION_TIME) TIME FROM V$BACKUP_SET WHERE BACKUP_TYPE='D'

GROUP BY TRUNC(start_time)) END, 

(SELECT TRUNC(start_time) dt, MIN(START_TIME) TIME FROM V$BACKUP_SET WHERE BACKUP_TYPE='D'

GROUP BY TRUNC(start_time)) STAR

WHERE END.dt = STAR.dt) 

ORDER BY dt ASC;
