**主机操作系统：**CentOS 7
**问题描述：**从 UI 上点击还原备份，还原至前一天的备份，然后就报错。
Failed to start backup server on all etcd nodes: [Failed to run backup server container, container logs: time="2022-09-08T01:48:19Z" level=fatal msg="listen tcp 0.0.0.0:2379: bind: address already in use" Failed to run backup server container, container logs: time="2022-09-08T01:48:26Z" level=fatal msg="listen tcp 0.0.0.0:2379: bind: address already in use" ]
我在其中一个etcd节点上重启服务器，然后查看如下：
[root@server149033 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ee316bb5a473 172.22.149.31:18888/rancher/rancher-agent:v2.5.14 "run.sh --no-registe…" 5 weeks ago Restarting (1) 41 seconds ago share-mnt
只有这一个容器，并且无限重启，查看日志如下：
