1.检查备份日志、2.检查配置文件哈希值 sha256sum /path/to/config 3.确认备份路径权限；目前就能想到这么多

3

查看日志信息

谢谢，这三项都查了，都没问题。我把备份目录换成 /tmp 或者换成 /home/tidb 等都可以备份。但是只要是 /app下面的目录就不行（/app/backup）。怀疑是不是因为/app 目录是数据库备份目录导致的

5

/app/backup里面有内容么？有的话能清理么？:thinking: 看你描述是目录有问题？
权限对么。

6

你换成app1/backup
改成777权限
chmod -R 777 app1/backup
