Question

If the main Vault server suffers a complete hardware failure, what specific state must the standby server be in to ensure zero data loss during the failover transition?

Accepted Answer

To ensure zero data loss during a failure, the standby server must be in a state called synchronous replication. This means the standby server is a perfect, real-time copy of the main server. When the main server saves a piece of data, it waits until the standby server confirms that it has also saved that same piece of data before moving on. Think of it like two people writing in identical notebooks where neither person turns the page until they are both sure the other has finished writing the current sentence. Because the standby server is always perfectly caught up, it has everything the main server had right before it crashed. If the standby is behind, even by a tiny bit, you risk losing whatever data was in transit during the switch. Therefore, the standby must be fully synchronized so that it can take over the job without missing a single thing.
