Then a backup will last forward for a long time.<br/><br/>I was starting to post the same idea you said nelisky.<br/></div><br/>Yes, I saw your other post and I really like the poll of addresses, but we still need a way to easily back up when those get all used, don't we? I know the address space is huge, but there might be applications that deliver thousands of addresses per day.<br/><br/><div class="quoteheader"><a href="https://bitcointalk.org/index.php?topic=921.msg11228#msg11228">Quote from: satoshi on August 26, 2010, 12:57:40 AM</a></div><div class="quote"><br/>How about a json-rpc command that locks the wallet, flushes it, copies wallet.dat to a location you specified, then unlocks it? That would be a smaller project than the pooled keys, so maybe it could be done first.<br/><br/>What's the simplest portable way to copy a file? Is there something in Boost?<br/><br/>What should it be named? maybe:<br/>backupwallet <destination><br/><br/><br/></div><br/>Great on all accounts, name and implementation approach. <br/><br/>As for the file copy, why add to the boost dependency? I for one would love to get a core lib with very little deps. In C++ you can just use standard file streams, can't you? Something like <a href="http://www.dreamincode.net/code/snippet2306.htm">http://www.dreamincode.net/code/snippet2306.htm</a> (out of a quick google, didn't try but looks correct).<br/><br/>To put the cherry on top, why not add a trigger that makes the copy whenever there's a change to the wallet? Well, this would depend on file locking to work properly and that sucks on windows iirc.
