windows – Robocopy,不要覆盖现有文件,而是复制已更改的/新文件

我编写了一个命令脚本/批处理文件,用于复制已修改的文件,但会根据脚本运行的日期创建树结构

例如我的树是一个特定的文件.

c:_archive201209
                    23
                        0930
                             Todays notes.txt
                        1145
                             Todays notes.txt
                    24
                        1000
                             Todays notes.txt

如果您觉得有用,我可以发布该脚本的示例.

由于受欢迎的需求,请在下面找到我的基本备份脚本.

@echo off
cls
rem parse the output of the date /t command to create a date in the format yyyymmdd,and also remove the delimiter (/)
rem  store the results in environment variables
for /F "tokens=1,2,3,4 delims=/ " %%i IN ('date /t') do SET Z_DATE=%%k%%j%%i 
for /F "tokens=1,4 delims=/ " %%i IN ('date /t') do SET Z_YEAR=%%k
for /F "tokens=1,4 delims=/ " %%i IN ('date /t') do SET Z_MONTH=%%j
for /F "tokens=1,4 delims=/ " %%i IN ('date /t') do SET Z_DAY=%%i

echo date %Z_DATE%
echo year %Z_YEAR%
echo month %Z_MONTH%
echo day %Z_DAY%

rem parse the output of the time /t command to remove the delimeter (:)
rem  store the result in an environment variable
for /f "tokens=1,2 delims=:. " %%i IN ('time /t') do SET Z_TIME=%%i%%j

echo time %Z_TIME%
rem change the colour to a nice deep green on black.
color 02

@echo on
xcopy "c:MyFiles*.*" "C:MyArchiveByDate%Z_YEAR%%Z_MONTH%%Z_DAY%%Z_TIME%%~p1%~n1" /ksymhr
@if @@ERRORLEVEL==1 SET Z_BACKUP_ERROR_FLAG=1

Goto End

echo An error occurred during the backup.
echo.
pause

:End

echo %Z_DATE%
echo %Z_TIME%
time /t

rem Clear out the environment variables
SET Z_DATE=
SET Z_TIME=
SET Z_BACKUP_ERROR_FLAG=

如果您对此脚本有任何疑问(我从主备份脚本中快速填写,并且未对其进行彻底测试),请在我的Gmail帐户中通过主题行“服务器故障备份脚本查询”向我发送电子邮件.如果您可以在不问我的情况下计算我的Gmail地址,那么我很乐意为您提供帮助.
