Do you have backup equipment?

I am a very responsible person, I give my very best on each and every wedding, I am always bringing with me two camera bodies with several lenses, but even that’s not satisfactory for me; I take back up to the next level: I have a high end cinema camera Canon C100 that records on two media cards simultaneously – providing instant backup of the footage. I record sound on two devices as well. I record directly on my camera through a wireless system and I am monitoring that sound at all times. The portable audio recorder is recording directly from the audio source. After that all of the footage sits on a Raid as well as another external HDD.
