[TiDB Version] v4.0.9
[Encountered Problem: Symptoms and Impact] When using TiDB’s BR command for a full database backup, does it by default back up system databases (INFORMATION_SCHEMA, METRICS_SCHEMA, mysql, PERFORMANCE_SCHEMA)?

If you don’t want to back up, you can use Dumpling to export the account information.

It seems that only version v4.0.9 will not be backed up.
