Local versions are on a Synology NAS. Which gets backed up more-or-less monthly to external hard drives using Truecrypt. One set of drives is saved at the house in a fire safe, and the older set is stored offsite at the office (which if I get fired can be abandoned without fear of disclosure).

Insurance documents are printed out and stored in a plastic tote. Along with the car title & house deed, some cash, passport and other important documents in case I have to evacuate for a hurricane. I can grab it and the cat carrier, and out the door I go.
