RMAN: Displaying current backup progress

To check the progress of your current RMAN backup use this script:

#This is my favorite script

select recid
 , output_device_type
 , dbsize_mbytes
 , input_bytes/1024/1024 input_mbytes
 , output_bytes/1024/1024 output_mbytes
 , (output_bytes/input_bytes*100) compression
 , (mbytes_processed/dbsize_mbytes*100) complete
 , to_char(start_time + (sysdate-start_time)/(mbytes_processed/dbsize_mbytes),'DD-MON-YYYY HH24:MI:SS') est_complete
 from v$rman_status rs
 , (select sum(bytes)/1024/1024 dbsize_mbytes from v$datafile) 
 where status='RUNNING'
 and output_device_type is not null
