I personally would think netbackup would be a better solution for this...
Also I would look at some solutions like Sonasoft....
They will create a redundant server on your site with all data being replicated constantly but with low bandwidth.
I think Netbackup is similar so I'd check that versus 11d
Also the solutions like Sonasoft offer restoral to dissimilar hardware. I personally haven't tested their solution yet but am always interested in that type of solution. I don't think that particular company supports oracle though...
Again... I would look strongly at Some of Symantecs Other Products though to complete this task but you could use 11D and use the Throttling of bandwidth and scheduling options it seems like.
