Used BR to back up data to MinIO, then encountered this issue. Has anyone else encountered the same problem? Totally confused…

Are the BR version and TiDB version compatible? Does the table mysql.tidb_runaway_watches not exist?

I don’t have the table mysql.tidb_runaway_watch in my v7.1.1, never seen it.

I downloaded the default br.

I haven’t seen this table in previous versions of TiDB either.

You should use the BR version 7.3, as TiDB only has this table in version 7.3. Switching to BR version 7.1 will work.

How do I change it? Is there a tutorial link?

When you download, you can specify the version number.
tiup install br:v7.1.1

| username: tidb菜鸟一只 | Original post link

Don’t you know you can just install it directly with tiup? tiup install br:v7.1.1

You can download the offline package using:
wget https://download.pingcap.org/tidb-community-toolkit-v7.1.1-linux-amd64.tar.gz

It is recommended to uninstall version 7.3 using tiup uninstall br:v7.3.0, otherwise, you will need to specify tiup br:v7.1.1 each time you use it.
