Title: Recovering Coins from a lost or destroyed computer.
Post by: justmyname on June 18, 2013, 02:54:03 AM
1 I have some of my Bitcoins on a laptop computer.

2 I have encrypted the Client (wallet) on the laptop and backed it up on a few removable usb drives. 
 
3 The encryption number is also saved.

As I see it. 

1 If my computer is lost or destroyed nobody will be able to steal the coins as they are encrypted.

2 I can simply get another computer. Install another Client (wallet). Import the (saved back up files) from the removable usb drives. This will restore my coins.   No loss.

Is this correct?

Yep, I change computer 2 months ago and recovered my wallet without problem.

the only thing you need to do is changes the wallet.dat

I change to an online wallet in blockchain.info because its faster than Bitcoin-QT. You can import in blockchain.info your wallet.dat without trouble.

Yes, that is basically right, presuming you have the latest wallet file.

But it also depends on which wallet you have. They do not all work the same

For instance with Electrum (electrum.org) which I use you don't even need  to backup the wallet file, because the entire wallet (list of private keys) can be recovered from a 12-word phrase you remember,  also known as a "deterministic seed".

That's what I thought. It's probably all the security I need.

I don't know all the details but I will be able to restore the Coins eventually.

 The version is QT 4.8.3.

I recommend you make a backup after every transaction you make, because of hidden change addresses that you don't normally see.

No need for that, with the default keypool of 100 pre-generated addresses a backup only after every 100 transactions is required.

Actually, 100 <= (sent transactions + generated addresses)
