Finding a better method....

Anyone have any great ideas on how better to organize the kids information in one place???? I wanted to put a copy of their b. certificate, ssn, shot records, IEP's and report cards... not really memoriblia stuff - mostly boring records and paperwork.....
Currently, I "try" to keep it in a 3 ring binder for each kiddo.... but I really want a backup plan in case of a fire or major disaster....

What do you do??
