How to backup your wallet using private keys

You can export your private keys from a MultiBit wallet into a file (using the 'Tools | Export private keys Export private keys' option) and, as long as you do not manually create new receiving addresses, you can use the private key file as a backup for the wallet.

If something happened to your wallet and you want to recreate it do the following:

  1. Create a new empty wallet.
  2. Import your private keys file using the 'Tools | Import private keys Import private keys' option.
  3. MultiBit then adds the private keys from the file into the new wallet and replays the blockchain to get the transactions.

Problem solved! How can I thank you?
MultiBit is "donationware" and all donations go towards development and server costs.
