I have a separate "safe" clip collection and keep everything there in addition to saving the emails as txt files...
Speaking of safe (har), I would suggest purchasing a small, fire-proof, WATER-proof fire-safe for storing discs that cannot be easily replaced. The smaller ones are not expensive, maybe $90 at an office supply chain. Size of a bread box, and capable of storing a few dozen DVDs.
"Media safes" are more expensive, but guarantee the internal temperature will not exceed a safe threshold and melt your DVDs.
"Water proof" is important, since if worse comes to worse your place does catch fire, what'll they use to put the fire out? Yeah. A fire-fighter buddy clued me in about this essential requirement. These safes have a rubber gasket around the door and really aren't intended for deep-sea diving; they just keep the rain out.
Sometimes you can get a bargain on damaged safes. I got my 24" cube media safe for $110 USD because the lock is broken. Who cares? Thieves don't want my family pictures.
Anyway, if you don't have a small safe -- look into it. It's like Murphy's law: if you have one, you'll never need it.
