If your Kubernetes cluster uses etcd as its backing store, make sure you have a
|
|
[back up](/docs/tasks/administer-cluster/configure-upgrade-etcd/#backing-up-an-etcd-cluster) plan
|
|
for those data.

|
|
如果你的 Kubernetes 集群使用 etcd 作为其后台数据库，
|
|
请确保你针对这些数据有一份
|
|
[备份](/zh-cn/docs/tasks/administer-cluster/configure-upgrade-etcd/#backing-up-an-etcd-cluster)计划。
