So, as many others, I need to backup wallet.dat. And since this one is on a server, I need it to happen unattended. And because this server is being used by the lottery, I must not shutdown bitcoind.
So far I just copy the file over, and do it often so I can outlive one corrupted file. But this is not ideal, as I should backup after every transaction (sent, right? no new addresses are created on receiving a transfer ) or after everytime I create a new address.
For that I thought about instead of copying the file I could use db_dump to dump it's contents, using the -r flag just in case. Would that work?
The ideal solution would be an rpc call that would either:
- flush and lock updates until a new rpc call (any call, didn't need to be an unlock command) would come over
- flush and cp wallet.dat to a side file
- flush and dump through jsonrpc. If each key would come separate in an array, we could then call this with 'lastseen=X' to just get new keys
Could this work? Which would work best?
