How does one back up DRM-protected content (locally)?

For example, supposed one has a DRM-protected .epub book from, say, Barnes-and-Noble.

If one wants to keep this .epub book for future use (say 5 years later) on a totally new ereader device, what does one have to have saved to be able to read this .epub then? Assume, for example, that one does not have access to Barnes-and-Noble at that 5-year mark.

Obviously, the .epub file itself. But, what does one need to unlock the DRM-protected .epub???

I arbitrarily chose the B&N example, because I understand that B&N is using a new "password-protected" scheme from Adobe. Is is sufficient to save just the .epub file and a textfile that reminds one of the email address and password (is it credit card number for B&N???)?

Bottom line: As any computer user will tell one, it is imperative to back up one's data - any number of things can go wrong. By backing up the right information, one should be able to restore one's data at any point in the future. This sometimes means backing up the data, a passkey, and even possibly the original program that "bound" the two.

How do all of you back up your books for perpetuity?
