Protecting Your Backup Media?

// asks: "How do you protect YOUR backups from destruction? Paper-based backups can survive most disaters (fire and even EMP) in a relatively low-spec firesafe/cabinet. Magnetic media (floppies, DAT, DLT) are much more sensitive to temperature (and EMP) - they won't reach anywhere near the magic 233C (or "Farenheit 451" if you prefer) at which paper bursts into flames. A higher specification firesafe is required for these. But what about CD-ROM; what temperatures can they handle? And we've all zapped CD's in a microwave - does this mean that they are particularly vulnerable to EMP too?"
