I'm on Linux, so I am not worried about virus attacks.  I back up my wallet.dat regularly to several pen drives.

Question:  I am mining so I usually have 4 or 5 transactions awaiting another 100+ block solves before they are confirmed.  Let's say I backup my wallet and something happens / need to restore it.  If I restore the a .dat - that was backed up with 4 partially confirmed transactions, will they be reconfirmed or lost?

Thx

They would be confirmed.

Buy a TREZOR! Premier BTC hardware wallet. If you're reading this, you should probably buy one if you don't already have one. You'll thank me later.

Has anybody made a live linux distro version for a wallet to a thumb drive setup ?

I've started a project that builds a modified Ubuntu Privacy Remix distro to create secure offline wallets, and execute offline transactions. Might be of interest to the readers of this thread. More details in the original post:

No wallet is 100% secure except an offline wallet where you do the hashing on an abacus... Its entirely possible (likely) a 0-day exploit will be discovered and you will lose every bitcoin handled by your client...

You don't have to do hashing to maintain a wallet. 0-day exploits only work on connected machines. So when using an offline machine to keep your keys you will not lose any bitcoin to a 0-day exploit. No abacus required, just scissors for the network cable.

No wallet can ever be completely secure. You can encrypt the hell out of it but the physical media you have it stored on can always become damaged. This is a great how to on making a decently secure savings wallet though. Very good information here. I will admit that I don't have enough bitcoins to even have a savings wallet yet but if I had any substantial amount of coins I would absolutely create a really secure wallet.

Hi,

I need some clarification, please.

Suppose someone steals my wallet.  What happens?
Is my file gone?
My file is not gone, but someone just copied it, set it up in his computer and transferred the coins  to one of his addresses?
How to I know that I was stolen?  When I try to send my coins to someone? At the next time I run the bitcoin client?

If someone steals your wallet.dat file (copied it presumably), the coins would be gone if he set it up in his computer and transferred the coins  to one of his addresses. On the next time you run the client your balance would be updated to show the newest balance. This is because the wallet.dat file holds the keys needed to spend the coins, and whomever gets the keys first can spend the coins first.

+1

1) Encrypted flash drive with separate os for your master wallet(s).
2) Unencrypted .dat files on cd, sd- or flash for relatives in case of ...

Only thing I would add is "Spread it out!". Don't keep all your BTC's in one file/wallet system.
Yes more annoying, yes more cumbersome, but the risk becomes allot smaller for every new system you add.

4/5 posts yay ....
