Hello everyone.  Do you think this would work in making a backup copy for wallet.dat file? http://ronja.twibright.com/optar/A 200kb file could be stored in a single A4 paper. The wallet would fit on a single A4 if this would be the case. |

No prob, probably someone here with advance technical skills could create a simple client to print our wallet. We could sleep at ease now knowing the wallet is still on the drawer.  |

You don't need all 200kb. All you need is the 32 byte private key for each Bitcoin address you have.
|
Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable. I never believe them. If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins. I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion. Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice. Don't keep coins online. Use paper or hardware wallets instead.

With Linux it's easy compile optar. I don't know what would happen in Windows.

Yes, Windows doesn't know what wallet.dat is so it fall backs to default assumptions... and very long ago before DVDs, we had VCDs, the video was stored in files that ended in .DAT |

Yes... to some extent. The wallet only holds 100 addresses initially, so if you use more than 100 addresses after making your backup, you will not be able to access the newer coins. So it would be wise to make regular updated copies of the wallet. Personally I run automated alternate backups to multiple locations. This way, if your wallet.dat gets corrupted (which happened to me, fortunately AFTER I started my backup routine), you won't accidentally over-write a good copy. |
