I'm trying to deploy an etcd cluster on GKE using the etcd-operator helm chart.

I've successfully got the cluster online and working, but now I'm trying to figure out how to backup the thing. If I'm understanding this issue and this issue, is it true etcd-operator doesn't actually support periodic backups?

It seems to me that including backup and restore operators is pretty useless if you can't backup your cluster on an ongoing basis.

Am I misunderstanding the documentation? How have other people solved this?

Here's the chart values I'm working with currently:

rbac:
  create: false
  apiVersion: v1beta1
  etcdOperatorServiceAccountName: vault-etcd-operator
  backupOperatorServiceAccountName: vault-etcd-backup
  restoreOperatorServiceAccountName: vault-etcd-restore

deployments:
  etcdOperator: true
  # one time deployment, delete once completed,
  # Ref: https://github.com/coreos/etcd-operator/blob/master/doc/user/walkthrough/backup-operator.md
  backupOperator: true
  # one time deployment, delete once completed
  # Ref: https://github.com/coreos/etcd-operator/blob/master/doc/user/walkthrough/restore-operator.md
  restoreOperator: false
