同步存量数据的步骤：
1) 通过 TiKV-BR 备份上游集群数据，并指定足够长的 `--gcttl` 参数。参考 [Backup Raw Data]。
1) 通过 TiKV-BR 备份上游集群数据，并指定足够长的 `--gcttl` 参数。参考 [备份 Raw 模式数据]。
> 注意：`--gcttl` 需要包括数据备份时长、数据恢复时长、以及其他准备工作的时长。如果无法预计这些时长，可以临时停止 GC（`SET GLOBAL tidb_gc_enable = "OFF";`，见 [tidb_gc_enable]），并在 changefeed 启动后恢复（`SET GLOBAL tidb_gc_enable = "ON";`）。
2) 记录步骤 1 备份结果中的 `backup-ts`。
3) 将备份数据恢复到下游集群。参考 [Restore Raw Data]。
3) 将备份数据恢复到下游集群。参考 [恢复 Raw 模式数据]。
4) 创建 changefeed，并指定 `--start-ts=<backup-ts>`。
