NoteThis feature is only available in Axon Server Enterprise versions 4.3 and higher.
axoniq.axonserver.replication.min-active-backups. The default value of this parameter is "1" which means that if you have Active Backup nodes, at least one of them needs to be up at any time. The higher the value set for this property, the higher the number of Active backup member nodes that need to be available for a successful transaction, so this property affects the availability of the cluster and hence needs to be carefully managed.
