可是我用的rawkv所以是裸kv集群，没有tidb
我尝试全量备份，backup-nfs.yaml如下
apiVersion: pingcap.com/v1alpha1
kind: Backup
metadata:
name: basic-backup-localstorage
namespace: tidb-cluster
spec:
toolImage: pingcap/br:v5.1.0
#backupType: raw
cleanPolicy: Delete
#storageClassName: local-storage
##Only needed for TiDB Operator < v1.1.10 or TiDB < v4.0.8
#from:
#host: ${tidb-host}
#port: ${tidb-port}
#user: ${tidb-user}
#secretName: backup-demo1-tidb-secret

运行20分钟以后出现如下错误
这是因为什么呢
