Wallet Protection

Question

Is there a way to mirror wallets among the multichain servers so that getaddressbalances looks the same from each server?  Is there a better way to achieve high availability resilience of account records (if the server hosting my wallet crashes, all of it's assets are apparently inaccessible)?

Failing that, what's the best way to backup a wallet?

Answer 1

You can use importaddress to have multiple nodes monitor the balance of a particular address, but not be able to spend its funds.

Or dumpprivkey + importprivkey to fully share the keys between nodes. Bear in mind that you shouldn't simultaneously issue transactions for the same address on multiple nodes if you do this.

You can also back up the wallet.dat file in your blockchain directory, which contains the private keys.
