redundant backups

User_U9EN2

Hi All,

Using Oracle 11gR2.

RMAN retention is set to redundancy 1.

I have a backup job of particular tablespace "TX1" running..for few hours, its almost completed.

By mistake I initiated the same backup job from another terminal. so the job was taking same "TX1" tablespace backup from 1st file..

I noticed my mistake and deleted the 2nd backup after some time.

So, say 1st 10 .dbf files are backed up 2x ..its in the same day.

Now how do I delete the 2nd redundant copy?

Thanks.
