"The only thing I haven't got in place is off site backup and I'm working towards that at my workshop."I lost the cr2 when my pc crashed so i only have the jpg on flickr.
I have used Carbonite as my sole back-up for the last 2 years. Works out very well at a low cost per year and it's all automatic, once set-up you don't have to do anything. It's already paid for itself when my PC crashed last year and all of my files, including 5,000+ pictures were safe and sound.
My only complaint about Carbonite is how long it takes to upload a week's worth of photos...actually more of a complaint about my internet connection, I guess. It's a very cheap and easy insurance policy.
