what is the incompatibility?

We already use BR for clustered index, there seems no incompatibility.

That's great! Looks like all we need to do is to add a check to prevent BR 4.0 to backup/restore TiDB 5.0.

we already have a version check since #311. major version mismatch (e.g. BR 4.0 ↔ TiKV 5.0) is disallowed.

Versions of the nightly release of TiDB and TiKV are wrong, TiDB shows 4.0.0-beta.2, TiKV shows 4.1.0-alpha 😢
