echo start bauckup mysql %date:~0,4%-%date:~5,2%-%date:~8,2% %time:~0,2%:%time:~3,2%:%time:~6,2% >>log.log
::关闭mysql服务
net stop mysql
::复制data目录
xcopy %DATAPATH% %SRCPATH%\ /e /y
::开启mysql服务
net start mysql
echo bauckup mysql finish %date:~0,4%-%date:~5,2%-%date:~8,2% %time:~0,2%:%time:~3,2%:%time:~6,2% >>log.log

::压缩数据库文件并删除
"C:\Program Files\WinRAR\WinRAR.exe" a -r -ep2 -ibck -inul -df -t %SRCPATH%.rar %SRCPATH%\
echo compress mysql data finish %date:~0,4%-%date:~5,2%-%date:~8,2% %time:~0,2%:%time:~3,2%:%time:~6,2% >>log.log

::++++++++++++++++++删除目录++++++++++++++
rd /q /s %SRCPATH%
