I got the idea originally, as well as example scripts, from the Oracle Press book Oracle Data Guard 11g.

It doesn't require previous RMAN backups so you don't have to worry about not using it now. Essentially it's duplicating the database across the network using RMAN.

Just be careful not to overrun your network connections if you're not using separate and dedicated network interfaces for data guard.
