code: public static ExtensibleConfigurationPersister createCachedRemoteDomainXmlConfigurationPersister(final File configDir, ExecutorService executorService, ExtensionRegistry extensionRegistry) {
          return createRemoteBackupDomainXmlConfigurationPersister(configDir, executorService, extensionRegistry);
      }
docs: --cached-dc, just use the same one as --backup, as we need to write changes as they occur.
