Preface

This article introduces a simple BAT script to back up Mysql under Windows. The script uses mysqldump Command to back up a specified Mysql database to a file. The file format is %dbname%-yyyyMMddHHmmss.sql. Only the backups of the last 60 days are retained. If you want to execute it regularly, just add a task schedule in Windows. For details, please refer to this article.

The sample code is as follows

@echo off
set hour=%time:~0,2%
if "%time:~0,1%"==" " set hour=0%time:~1,1%
set now=%Date:~0,4%%Date:~5,2%%Date:~8,2%%hour%%Time:~3,2%%Time:~6,2%
echo %now%
set host=xxx.xxx.xxx.xxx
set port=3306
set user=root
set pass=root
set dbname=dataname
set backupfile=E:\backup\db\%dbname%-%now%.sql
E:\backup\mysql-5.7.13-winx64\bin\mysqldump -h%host% -P%port% -u%user% -p%pass% -c --add-drop-table %dbname% > %backupfile%
