Overview of TiDB Backup & Restore Architecture

As described in TiDB Backup & Restore Overview, TiDB supports backing up and restoring multiple types of cluster data. You can use Backup & Restore (BR) and TiDB Operator to access these features, and create tasks to back up data from TiKV nodes or restore data to TiKV nodes.
