Your photo backup routine??

One of the external drives is 750 gb and 2 are 2 TB.  I have done very little shooting since I bought my D800 in June because it's been in the shop 4 times.  Once I get going, assuming I eventually get it back fixed, I'm planning on upgrading the capacity on all of my external drives and installing a 3 TB back-up drive in my computer so I've got the capacity for internal back-up of all my photos on my PC.

That's my story and I'm sticking to it.
