The official documentation says that BR cannot restore system tables, but I tested it today and found that the data in the mysql.user table can be restored. What’s going on?

  1. Created 2 users, which can be seen in the mysql.user table.
  2. Full backup with BR.
  3. Restored with BR and found that these 2 users can still be seen in the mysql.user table.

Which version are you using? What is the restore command, and did you explicitly specify restoring the system table?
