# `BR` Architecture
+ `BR` sends a backup or restoration command to each `TiKV` node 
+ `TiKV` performs the corresponding backup or restoration operation
+ Each `TiKV` node has a path in which the backup files generated in the backup operation are stored and from which the stored backup files are read during the restoration
