You will want to create multiple backups of your private key. This is true for both quantity and type of backup. If the CD you copy the private key to is defective and gets corrupted then you would have no way to recover your lost money |

If the CD you copy the private key to is defective and gets corrupted then you would have no way to recover your lost money Oh.. I have like 8 USB's and 6 CD's, 2 HD's, 1 External HD. I used a CD to move them off the offline HD so nothing could be copied from the HD but what I wanted. Then backed it up like a mad man.. I don't know if I am done backing up actually.. Kinda had some crazy plans to plant them around a large area in weather proof containers.... yaa.. LOL .. PROTECTION PROTECTION PROTECTION. Was going to go to factory direct to buy a but ton of CD's. |

Isn't this overkill? And why not just use Trezor, as mentioned above?? It keeps the master public key when disconnected, unless you click "forget device".
If you don't want the master public key exported you'll have to use another non-web wallet service like Electrum.

Do you really have to do this? Can't you just: --> Disconnect from internet --> Boot from a live Ubuntu disc/USB --> Run a wallet like MultiBit, generate offline addresses --> Copy/write keys to DVD, print paper wallets --> Shut down the PC |

I'm not debating it's longer than it needs to be.. just curious about it's point of failures. As far as I can tell it is only the encryption pass. |

Next time when NASA launches a rover to Moon or Mars, I will send my private keys with it to be planted there, just to be sure of being protected from any apocalypse. BITCOIN TO THE MOON, LITERALLY!!  |

seems too complicated to do to backup your wallet address, I think you only need to wear blockchain.info for your wallet, and let the wallet system that protects the security of your account and bitcoin ...  |

Destroying hard drive seems a little expensive.
Try this:
You will need two USB drives
Disconnect all the internal drives
create one live Ubuntu/Tails or any other linux USB
on 2nd USB create encrypted container*
transfer bitcoin wallet address generator to 2nd USB and run it from Live USB
create Bitcoin addresses and save them on 2nd USB
(optional but highly recommended) encrypt your private keys with strong password.
**important** create many back up copies
*cross platform encrypted container is hard to find since TrueCrypt (the only cross platform container that I know of) is no longer in development.
Edit:
as an added layer of security, use a spare computer that will never go online to generate Bitcoin addresses
