Dear all,I've been asked a question by an SR user about where to store back ups for your Bitcoin wallet?I've taken a look at https://en.bitcoin.it/wiki/Securing_your_wallet#Backup suggests using Wuala over other cloud storage providers as the service doesn't store copies of your encryption keys. I understand it's now possible to encrypt your wallet with a passphrase.My suggestion for what it was worth was to place the wallet.dat file inside a Truecrypt container, protected with a sufficiently complex password and most importantly a key file (http://www.truecrypt.org/docs/?s=keyfiles) and only then use a cloud based storage service.The alternative of course is just to back up your wallet on to a thumb drive or DVD but of course this wouldn't be much help if your data was lost or stolen.Looking forward to hearing all your thoughts.V.
