Maybe I read this tip here in the past but I have used it and past on it on since:

Color scan your credit cards, Driver license, passport, birth cert, etc and email them to a web based email account.

If you lose any of them you can usually find a pc to get them from online. How they're accepted by officials is another matter but I always feel safer knowing I have a back up only I can get to.

When I travel I generally email myself a copy of flight information and pre-scheduled route maps and important phone numbers (like to cancel stolen cards) as well as a copy of my insurance cards or event registration information. I have amazed myself at what I can destroy or lose or get wet and make unreadable/unusable.
