Title: Save your wallet on paper Post by: dreich on August 04, 2011, 01:42:44 AM Hello everyone. ;D
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. Title: Re: Save your wallet on paper Post by: ffuentes on August 04, 2011, 01:49:39 AM It's so interesting, thanks.

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. ::) Title: Re: Save your wallet on paper Post by: casascius on August 04, 2011, 01:56:55 AM You don't need all 200kb. All you need is the 32 byte private key for each Bitcoin address you have.

Is wallet.dat the ONLY file I need to backup in order to keep my bitcoins in my walled if my HD fails? 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. |
