Which tapes are the backups on?

Not really necessary as RMAN can work it out but if you need to know...

select media
, to_char(completion_time,'DD-MON-YYYY HH24:MI:SS') backed_up
from   rc_backup_piece
where  1=1
and    db_id           = 4053457814
and    completion_Time > sysdate - 2
order  by 2
