Recovering wallet

[petermeuris]

Hello all,

I have an encrypted wallet.dat backup from half a year ago, and want to recover its content.

1/ Downloaded bitcoin-0.6.3-linux
2/ Added the wallet.dat in  ~/.bitcoin
3/ Downloaded the blockchain.

However the sum of all the (ca 200) transactions is not equal to what I knew was the total amount in the wallet.

4/ I did a -rescan, but no change.
5/ I did not create extra addresses other than the default ones, to my knowledge.

Still I lost some coins ....

Any advice here ?

I have an encrypted wallet.dat backup from half a year ago, and want to recover its content.

How many total "spends" have occurred since the backup was made?

By default the wallet has a keypool of 100 keys.  These are 100 "future" keypairs.  Each "spend" (outgoing tx) uses 1 new key from the keypool for change.  Each time you request a new address for incoming tx uses a key.  If you used more than 100 keys since the backup was made then any tx past the first 100 are irrevocably lost.

After import some of the transactions show n/a as address. What does this mean ?

After "import"?  Do you mean after restoring the wallet.dat, or, are you actually importing -- i.e., trying to use pywallet or something to manually import the keys from the old wallet?

Also, you might try -upgradewallet, perhaps if there is a data corruption problem that the upgrade to the current format will resolve it?

But, make sure to not delete or overwrite your backup from six months ago, just in case.

No, that won't help. If there was a corruption, 0.6.3 would complain whether it was an old or a new wallet.
