Question

我具有以下目录结构：

\Users\DorrisPringle\Desktop\test
\Users\DorrisPringle\Desktop\test\mycopy.bat
\Users\DorrisPringle\Desktop\test\backup
\Users\DorrisPringle\Desktop\test\backup\asdf.txt
\Users\DorrisPringle\Desktop\test\backup\a_directory
\Users\DorrisPringle\Desktop\test\backup\a_directory\qwer.txt

如果密钥文件不存在，我想将backup / *复制到目录“ test”中。这是从mycopy.bat执行的：

if exist "\Users\DorrisPringle\Desktop\test\myservice.exe" (
    echo "all is good."
) else (
    robocopy "\Users\DorrisPringle\Desktop\test\backup" "\Users\DorrisPringle\Desktop\test" /MIR /R:1 /W:2
)

这给了我以下错误，最终只是删除了“ test”目录中的所有内容。我可以使用robocopy将测试目录中的所有内容复制到备份目录中，但是似乎无法正常工作。

Answer 1

/MIR开关等效于/E /PURGE

/PURGE指示robocopy删除目标（测试目录）中源文件（备份目录）中不存在的所有内容，然后再开始处理文件，但是由于备份目录本身位于目标文件中它也会被删除。

只需将/MIR替换为/E开关

批处理robocopy正在删除我的所有文件
