As a former wedding photographer, I typically went by the number of pictures I was willing to trust to a single card. Since file sizes went up at roughly the same time as storage sizes, I ratcheted up the maximum size SD card I'd use.

It used to be "won't use larger than 2GB". Right now it's around 8, but will likely become 16 in a couple of years.

Sounds like someone should do a 'RAISD' for cameras.

Higher end DSLRs (including mid-line ones like the Nikon D7000) support two SD card slots and "backup" mode where both cards are written to with every picture. That's probably enough for most paranoia.

One day I will have an original idea. Today is not that day.

Don't worry. I'm bankrupt on those, too.

Canon 5D Mk III has both SDXC and CF slots that you can duplicate as you shoot.
