What do you want?
End the backup with the corruptions or fix the corruptions?

Hi , I had a Similar problem during Rman Backup and we tried to set maxcorrupt for that datafile (in My case 32) to like 5 and edited the Rman command in as below

set maxcorrupt for datafile 32 to 5;

You can try to do that and check or go to support.oracle.com and read this Document

Handling Oracle Block Corruptions in Oracle7/8/8i/9i/10g/11g (Doc ID 28814.1)
