Hello all, i expose the issue i have with an Oracle server recover:

I use the rman to recover a Datafile into my oracle server and i start getting messages that some data can`t be read, then starts failoving in older backups searching for good versions of that data, but it seems that in all backups are the same corrupt data, and the recover fails. So the question is how can i backup all the Datafile including the corrupt data?

Thanks.
