World Backup Day today -- how are you saving your stuff?

I really don't back anything up. What is it that you think you are going to lose? Got pictures, put them on a hard drive or thumb drive "so you can use them" or don't be concerned about them and let them go it things go tits up.
We all have a bunch of cr4p we don't need on our computers so if I do something stupid enough to lose it all I am completely OK with that. I don't keep anything I can't afford to lose on a computer and neither should you!
