Title: Restoring old backups of wallet.dat Post by: berlin on May 21, 2011, 09:24:28 AM Are there problems with this? Say you backup a wallet.dat, save it somewhere. The next time you run the client it generates for you a new wallet.dat. Months go by, now you wish to spend bitcoins in old wallet.dat. Can there be a problem from this if you merely copy back the old save from months before?

might be good idea to start the bitcoin client with the -rescan switch to search for eventual transactions related to the old wallet from the time it was offline might recalculate available balance to be accurate.

This should not be necessary anymore since 0.3.21, since information about the current best chain is stored in wallet.dat, and a rescan of the unknown part is issued when this does not wallet the block chain database. If either the last version to write to wallet.dat, or the version to restore with is older, -rescan is needed.

Not many "average" users of the Bitcoin client would know how to add the -rescan command whilst starting the Bitcoin client. |
