批处理自动备份并生成日志文件

在windows里新建一个计划任务定期去执行以下脚本，脚本会自动执行备份任务，并记录执行结果到日志文件。（执行时间，备份是否成功）

@echo off
@echo ************************************************************
@echo.
@echo   Backing up data files ,Please do not close this Window!
@echo.
@echo ************************************************************
set sourcePath=I:\050_Manufacturing\050_Lean_KPI\A3 Database_201907\DB
set destPath=I:\050_Manufacturing\050_Lean_KPI\A3 Database_201907\Backup
set ETime="%date%-%time%"
If Not Exist "%sourcePath%" (
   echo Couldn't find database file Please check that! 	
   echo Failed:%ETime%>>"%destPath%\log\BackUp.log"
   
) else (
   xcopy "%sourcePath%\*"  "%DestPath%\*" /Y /Q /S
   echo Success:%ETime%>>"%destPath%\log\BackUp.log"
   
)

timeout 20
exit
