Also alfmad, you will need to make a new copy of the wallet.dat after using the wallet a few times even if you don't create any new wallet addresses yourself. And by using the wallet I mean sending funds plus also yes every time you create a new wallet address. As if FairCoin wallet is the same as Bitcoin one it creates a new change address after every 100 outgoing transactions iirc. You could also back your wallet.dat up in the cloud once you have encrypted your wallet. Like in a free Dropbox, Google Drive or SpiderOak account. In case your USB stick is ever lost or damaged.

Uhhh, what ?? Is this true Huh

if yes then this is completely new to me.
I was under the impression that a backup of the wallet.dat file is a backup that can ALWAYS be restored.
But now I understand that you have to make regular copies ( Huh

)
Can you please explain why this is so ? And if I just have my initial backup, what will happen if I restore after I've done alot of transactions ?

A wallet.dat can always be restored. Although I think for Bitcoin and most clones the wallet creates a new change address for transactions. At least every 100 transactions. As when you make a TX all of the coin at an address that is not needed to fulfill the transaction is returned to you as part of the same transaction. So you only need to do new backups of your wallet.dat when creating new wallet addresses. Or if the wallet gets used for sending lots of transactions.

The following Bitcoin wiki page helps explain transaction change addresses more -

https://en.bitcoin.it/wiki/Change - The wallet file contains the private keys for change addresses, and they can receive and send coins normally. However, the GUI in the default client does not display them in the address book, therefore a recommendation is to backup wallet.dat every 50 transactions.

Aha, ok, I understand ! Thank you for explaining Cheesy

So every transaction/ minting action will cause my wallet to create a new adress from an initial pool of 100 adresses.
Once these are all used, the wallet creates 100 new ones and these will need to be included in the backup by creating a new backup at that time.
So for for all my wallet.dat files of coins that I hardly ever use, I am luckily still save Cool

Thanks for notifying us of this ! Cool
