#1.备份

ETCDCTL_API=3 etcdctl snapshot save snapshot.db

恢复

 

#2.查看备份状态

ETCDCTL_API=3 etcdctl  snapshot status snapshot.db -w=table

#3. 还原快照

kubectl  cp /root/temp/snapshot.db  -n ingress-apisix  apisix-etcd-0:/tmp/

kubectl  cp /root/temp/snapshot.db  -n ingress-apisix  apisix-etcd-1:/tmp/

kubectl  cp /root/temp/snapshot.db -n ingress-apisix  apisix-etcd-2:/tmp/
