使用 mariadb-binlog --flashback 參數恢復 MySQL binlog 刪除的數據

原創黃山谷 2025-08-11

使用 mysqlbinlog 去實現 drop table恢復刪除數據只能根據備份+追蹤到刪除前的position 去恢復數據,如果delete 只能恢復到刪除前的一個 position/date，不像 binlog2sql、mysqlbinlog_flashback ，一些三方工具支持 flashback 的功能。

對比基于binlog 的恢復方式。（自己總結的，估計大佬們有其他高端姿勢，哈哈?。?/p>

工具	恢復方式
mysqlbinlog	可以恢復到刪除前的一個 position/date
mariadb-binlog	提取出兩個 position/date 之間刪除的語句，反寫插入 sql
mysqlbinlog_flashback	指定 schema table 就可以輸出，反寫插入 sql
binlog2sql	提取出兩個 position/date 之間刪除的語句，反寫插入 sql

查看 mariadb 的文檔，發現 mariadb 的 mariadb-binlog是支持–flashback的，既然這樣我們可不可以用 mariadb-binlog去恢復 mysql 的 binlog 呢？

環境準備：
mysql 8.0.39
rhel 8.10

這里就用墨天輪的 hr schema 一張 jobs 是表做測試

mysql> select * from hr.jobs;

19 rows in set (0.00 sec)

直接 delete 表

mysql> delete from hr.jobs;
Query OK, 19 rows affected (0.00 sec)

mysql> select * from hr.jobs;
Empty set (0.00 sec)

查看正在使用的 binlog

show master status;

show binlog events in 'mybinlog.000013';   
找到 delete 的 position 起始點
--105794   --106716

找到/bin/mariadb-binlog 上傳到 mysql bin 目錄下

可以看到 mariadb-binlog 是支持 --flashback

mariadb-binlog --help

···
 -B, --flashback     Flashback feature can rollback you committed data to a
                      special time point.
···

那我們來嘗試下恢復

mariadb-binlog /mysql/data/mybinlog.000013 -vv --start-position=105794 --stop-position=106716 --database=hr --table=jobs --flashback

[mysql@node5 backup]$ mariadb-binlog /mysql/data/mybinlog.000013 -vv --start-position=105794 --stop-position=106716 --database=hr --table=jobs --flashback

好像有報錯，但是數據好像是恢復了。

突發奇想，沒有在生產上驗證，請勿在生產上操作。
