本人之前用powershell 寫了1個備份文件的腳本

http://blog.csdn.net/nvd11/article/details/58375519

但是由于巨量問下搜索的性能問題..(原來powershell是.net寫出來的，真是垃圾)， 不得不用bat重寫了..

需求跟原來的是一樣的：

需求1： 檢查每個文件的修改時間， 如果小于日期參數， 則備份（和刪除）；

需求2：保留被備份文件的目錄結構。

windows bat下的forfiles還能一用， 當然用起來不能跟linux的find比

archive.bat

@echo off setlocal enabledelayedexpansion set sPathFrom=%1 set sPathTo=%2 set iDaysBefore=%3set cnt=0 :loop if "%1"=="" (echo %cnt%) else (set /a cnt+=1&shift /1&goto :loop)if %cnt% lss 3 (echo Usage: %0 ^<^<Source Path^>^> ^<^<Destination Path^>^> ^<^<beforeDate^>^>goto errorEnd )set sDateToday=%DATE:~0,10% set sLogPath=%cd%\logs set sLogFile=%sLogPath%\archive%sDateToday%.logif exist %sLogPath% (echo log path is existed! ) else (md %sLogPath% ) rem replace / to - set sLogFile=%sLogFile:/=-% echo log file is %sLogFile%echo source path is %sPathFrom% >> %slogFile% echo Destination path is %sPathTo% >> %sLogFile% echo archive files whose modified date is before %iDaysBefore% days>> %slogFile%rem get the string len... set n=0 :her set u=!sPathFrom:~%n%,1! if not "!u!"=="" (set/a n+=1 goto her ) forfiles /p %sPathFrom% /s /d %iDaysBefore% /c "cmd /c %cd%\archiveCore.bat @path %sPathTo% %n% >> %slogFile%"rem exit 0;:errorEnd rem exit -1;

archiveCore.bat 這個被上面的調用

@echo off setlocal enabledelayedexpansionset sFileFullName=%~1 set sFileName=%~n1%~x1 set sPathTo=%2 set lenGap=%3rem get the string len... set n=0 :her set u=!sFileName:~%n%,1! if not "!u!"=="" (set/a n+=1 goto her ) set iNameLen=%n%echo %sFileFullName% echo %sPathTo% rem echo %lenGap%set sFilePathTo=%sPathTo%\!sFileFullName:~%lenGap%! set sPathTo=!sFilePathTo:~0,-%iNameLen%!rem echo %sFilePathTo% rem echo %sPathTo%if exist %sPathTo% (echo path is existed! ) else (echo creating folder %sPathTo%md? %sPathTo% ) if exist %sFileFullName%\nul (rem it's a folderif exist %sFilePathTo% (echo path is existed!) else (echo creating folder %sFilePathTo%md? %sFilePathTo%) ) else (echo copying %sFileFullName% To %sPathTo%rem pausexcopy /y %sFileFullName% %sPathTo%echo removing %sFileFullName%del %sFileFullName% )

最后吐個槽， bat下字符串長度的方法要自己寫， 真是mdzz！

還有1個日期處理是坨屎
