Not .25 25 btc.

I thought maybe the network needed to just update the blocks.

I don't understand the point of backing up wallets then.. say I backup my wallet everyday, or week or whatever,
but between the last backup and the latest, I have spent some coins... and then my computer blows up
and I install the last backup... I thought the network was supposed to detect my key and automatically bring me back to the proper amount of coins I should have... if it just give me an invalid wallet... isn't this just as bad
as losing all your coins?

I don't get it. This is why I tried this only when I had 0 coins... I figured it might initially show the last coin account from the backup wallet but then update itself through the network to the real amount of coins that specific wallet key is supposed to have? Isn't that how it's supposed to work?

Am I doing something wrong? Note these are not two separately created wallets - I have those.. this is the same wallet, just a backup of a day earlier.

Every transactions is logged in the blockchain. So, everytime you use the bitcoin client it check the private keys in your wallet with the blockchain and find your bitcoins.

If you spent that bitcoins then try a -rescan

As for regularly backupping it, the problem is that if you use a different address everytime then your wallet will contain more private keys. If your backuped wallet is an OLD one, it may not have the new keys. So, if you lose your wallet and you use the backuped one, it doesn't have the recent keys and you lose the BTC attached to these recent keys. A bad thing
