I'm kinda a paranoid freak about house fires so I have everything backed up to an EHD but also to DVDs or flashdrives that are in a safe deposit box with my important papers at the bank (and yeah, I know the bank can burn down, but hopefully not the same night my house does
).
If I've done a backup and haven't made it to the bank yet, the drive/disc goes into my purse, which goes next to my bed every night so that I have my car keys and wallet next to the bed to easily grab in event of a fire without having to search for it - grab and go. Told you I was paranoid about fires!
