Preparing for dynamic cluster migration, can I specify a TIKV node to run the backup during the backup process?

Backup is handled by the leader of each region, and each TiKV node needs to output the backup SST files, unless you concentrate all leaders on the specified TiKV node.

BR cannot specify a TiKV node to run the backup, it pulls data from all TiKV nodes.

Under normal circumstances, all KV nodes will run backups.

Dynamic migration should not conflict with BR backup. Is there any concern or specific requirement?
