set mysql_dump="C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqldump.exe"
set Ymd="%DATE:~0,4%%DATE:~5,2%%DATE:~8,2%%TIME:~0,2%%TIME:~3,2%"
set backup_path="D:\mysql_backup"

set var=%errorlevel%
@echo on
if %var% EQU 0 (
echo "%DATE:~0,4%-%DATE:~5,2%%DATE:~8,2%-%TIME:~0,2%%TIME:~3,2% backup success!" >> %backup_path%\logs\mysql_backup.log
) else (
echo "%DATE:~0,4%-%DATE:~5,2%%DATE:~8,2%-%TIME:~0,2%%TIME:~3,2% backup fail!" >> %backup_path%\logs\mysql_backup.log
