Which keys need to be copied to the Cluster Vault server?

All of the keys listed are essential components that must be copied to the Cluster Vault server for it to function properly.

The VaultEmergency.pass is critical as it provides administrative access to the Vault in case of emergencies or failures. It acts as a safeguard to ensure that proper access can be restored when needed.

The Encryption.key is vital for the security of data stored in the Vault. It enables the encryption and decryption processes, protecting sensitive information from unauthorized access. Ensuring that this key is present on the Cluster Vault server is crucial for maintaining the integrity and confidentiality of the stored data.

The ReplicationUser.pass is necessary for the replication process between Vaults in a clustered environment. This password allows authenticated communication between the Vault servers, ensuring that data replication occurs smoothly and securely, which is pivotal for redundancy and disaster recovery operations.

By ensuring that all of these keys are copied to the Cluster Vault server, you enable it to function as intended, facilitating secure access, data protection, and effective replication processes within a clustered setup.
