使用Robocopy仅复制更改的文件?

标签: asp.net msbuild web-deployment robocopy

我正在尝试找到一种简单的方法,只将已更改的文件部署到Web服务器以进行部署。在过去我曾经使用过MSBuild,可以告诉他只复制比目标文件更新的文件,但是我很着急并且不想试图找出更新版本的MSBuild。

我可以使用ROBOCOPY吗?有一个排除选项列表,其中包括:

  • / XC :: eXclude更改文件。
  • / XN :: eXclude较新的文件。
  • / XO :: eXclude旧文件。
  • / XX :: eXclude eXtra文件和目录。
  • / XL :: eXclude孤独的文件和目录。

排除究竟是什么意思?排除复制或排除覆盖?例如,如果我写了:

ROBOCOPY C:\ SourceFolder \ ABC.dll D:\ DestinationFolder / XO

这会只复制较新的文件,而不是相同年龄的文件吗?

或者有更好的工具可以做到这一点吗?

回答你的所有问题:

我可以使用ROBOCOPY吗?

是的,RC应符合您的要求(简单,只需复制所需的内容)


排除是什么意思?

它将排除复制 - RC称之为正在跳过


/XO选项是否只会复制较新的文件,而不会复制相同年龄的文件?

是的,RC只会复制较新的文件。将跳过相同年龄的文件。

(正确的命令是robocopy C:\SourceFolder D:\DestinationFolder ABC.dll /XO


使用/MIR选项可能对您有用。通常,RC比单个文件更适合目录和目录树。

您可以使用robocopy复制带有存档标志的文件并重置该属性。使用/ M命令行,这是我的备份脚本,只有很少的额外技巧。

此脚本需要NirCmd工具来保持鼠标移动,以便我的机器不会进入睡眠状态。脚本使用锁定文件来判断备份脚本何时完成并且mousemove.bat脚本已关闭。你可以放弃这部分。

另一个是7-Zip工具,用于拆分小于4GB文件的虚拟机文件,我的目标文件夹仍然是FAT32,因此这是必需的。我应该使用NTFS磁盘但尚未转换备份磁盘。

看起来/e选项就是您所需要的,它会跳过相同的文件/目录。

robocopy c:\data c:\backup /e

如果你运行两次命令,你会发现第二轮比较快,因为它会跳过很多东西。
