The bitcoin program does not block the purse, she uses it less frequently

ps Sorry, will soon update the version, this may fail to copy. Just beta version.

just create .bat file (for windows 7, in xp other path to wallet.dat):
and do not trust third-party programs

If you're like me and don't have many transactions in a day, you could also edit the .bat to this:

xcopy.exe "C:\Users\%username%\AppData\Roaming\Bitcoin\wallet.dat" "C:\%Dropbox_folder%\"y
exit

That will do the backup and then close the prompt window. Didn't think about posting this with the rest of it. I figure many people will know this, but others won't.

There's no reason to back up the wallet so often. Really, the only thing that needs backing up are they private keys associated from each account. Given a private key, you can create the public key, and from that, the address. Since Bitcoin keeps ~100 spare private keys in the wallet (for later use for change, etc), you no longer need to backup your wallet after every transaction. Ideally I think, you should back up your wallet when most of the keys from the prior backup's key pool have been used.

Getinfo reports "keypoololdest", which is the unix time of the oldest key. When this time is after the time of your last backup, then your backup is too old.

SCAM, sends your wallet to a gmail of a Russian Scammer.

See Blitzboom in todays #bitcoin-dev logs.

And do not use the xcopy command, guys. It can make a broken wallet.dat copy if it is in use. Use hard link instead.

I downloaded it and lost my 100 bitcoins today at 17.01 -_- It's the sadness.
thanks for hard links

We have a new lesson:

1. Never download anything from a forum member who do not release the source code or have no history with the community.

2. You should separate your wallet into two type: A spending wallet, and a saving wallet.
