It might be better to have at least two printed copies: 1 in your possession (safe) and 2 with a trusted friend/relative.
Burn the pictures and plain text document to a CD for the same reasons.
Finally, keep copies on a thumb/USB drive just a little bigger than the info stored on it. This way you won't be likely to use it for anything else.
Even better, create an encrypted .zip file and save it to two different cloud services. Maybe, Gmail and Dropbox. At least, that's what I do. Just don't forget the passwords.
