How to do etcd backup and restore if the certificates and the etcdctl only works on worker nodes? Please help

I don’t understand your question we do backup from master node because there we configured the etcd db, I don’t know if you created another etcd for nodes too … , so I think you can follow the same steps etcdctl --endpoints=<https://127.0.0.1:2379> --cacert=/etc/kubernetes/pki/etcd/ca.crt --cert=/etc/kubernetes/pki/etcd/server.crt --key=/etc/kubernetes/pki/etcd/server.key snapshot status /opt/snapshot-pre-boot.db
