etcdv3_backup.dbis dumped on master nodes of PMK clusters if Etcd backup is disabled, before a couple of operations and present at location/var/opt/pf9/kube/etcd/etcd-backup
It is recommended to backup your Etcd key value store to help recover from unplanned cluster outages. To enable, refer Configuring Etcd Backup
