Cloning from backups of standby database

I am on 11gR2. I have a physical standby database set up for a prod. I need to schedule backups on the standby database instead of primary. Can you please explain me in brief how to backup a standby database like whether should I cancel the recover managed mode, should I open the standby database?
I need to clone a database using these backups taken on the standby site.
(like duplicate database to xxx backup location '/backup/xxxxx';)
I dont want to use active duplication.

Any help in assisting me would be grateful.

Personally, I haven't done this, but the documentation seems to have a pretty good guide on how to do this:

Simple way,
shutdown the standby database
Take a cold backup
start up the standby in normal recovery mode and continue the recovery
using the backup, u can create a clone on any server.

This may require couple of hours downtime. Missed Recovery can be covered after the database is started.
Otherwise RMAN can be used as mentioned in the above post document. this needs a little more professional hands on exposure
