【 TiDB 使用环境】生产环境
【 TiDB 版本】6.5.0
【复现路径】删除原有的log备份任务，重新启动一个log备份任务，然后就报错。推测是原有的log备份任务没有被正确的删除
【遇到的问题：问题现象及影响】

已经有log备份任务在运行
可以查看log备份状态：tiup br log status --task-name=pitr --pd “${PD_IP}:2379”
kubectl get backup -A 还能看到之前的备份任务不？ 新起得任务配置文件怎么写的
由于有数据备份，直接重建集群恢复了。然后在测试集群无法重现问题。谢谢两位~
参考 https://docs.pingcap.com/zh/tidb-in-kubernetes/stable/backup-to-aws-s3-using-br#停止日志备份
目前逻辑是需要先停止已有任务，如果任务还在可以直接编辑停止，如果任务已删除，可以部署个 logStop: true 的新同名任务
