我的库非常小，如下是备份所需的时间记录：
===== 开始备份数据库 [dzdz] =====
[2022/07/21 01:00:01.910 +08:00] [INFO] [config.go:158] [“detect server type”] [type=TiDB]
[2022/07/21 01:00:01.910 +08:00] [INFO] [config.go:176] [“detect server version”] [version=4.0.6]
[2022/07/21 01:00:50.422 +08:00] [INFO] [main.go:216] [“dump data successfully, dumpling will exit now”]
不到1分钟就完事了。
