准备crd资源，从旧集群导出

旧的集群上执行备份

miniopodname=`kubectl -n zadig get pod -l app=minio|grep -v NAME|awk '{print $1}'`
kubectl -n zadig annotate pod/$miniopodname backup.velero.io/backup-volumes=kr-minio --overwrite
kubectl -n zadig annotate pod/kr-mysql-0 backup.velero.io/backup-volumes=data-kr-mysql-0 --overwrite
kubectl -n zadig annotate pod/kr-mongodb-0 backup.velero.io/backup-volumes=data-kr-mongodb-0 --overwrite
velero backup create zadig-20230717 --include-namespaces zadig

新的集群上（如果存储类发生变化需要创建以下文件）

创建一个声明yaml文件

vi change-storage-class-config.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: change-storage-class-config
  namespace: velero
  labels:
    velero.io/plugin-config: ""
    velero.io/change-storage-class: RestoreItemAction
data:
  nfs-storage: rook-ceph-block

kubectl create -f change-storage-class-config.yaml

velero restore create --from-backup zadigbak
