What happens when the flash inside the arduino hits 10,000 writes and dies ?
Nothing is backed up, unless you have at least 3 copies of it. One physically at a different location (fire,flood,volcano,earthquake,...)
Another thing is what happens when the owner of the wallet.dat file ultimately dies (through accident or natural causes) and brings the security pass phrase with them to the grave ?
Yes the value of bitcoins increases for everyone else as there are fewer coins, but that is of no help to the remaining living family who are broke.

Use redundant, checksum'd EEPROM (3+ chips with the data written to it in encrypted form).
You can get a good 100,000 writes out of each. Then when the time comes, you get a little warning light that says "Replace me bitch!" and you can swap out the EEPROM chips for new ones. Old data is copied to the new chips, verified, and then the rest of the chips are swapped out and written to with the existing data. Ill make a visual aid in paint real quick....
Whats that? Spelling? I cant hear you lalalala!
