The situation: I have a pieceofcrapuous laptop. One of the things that make it pieceofcrapuous is that the battery is dead, and the power cable pulls out of the back with little effort.
情况:我有一台笔记本电脑。让它变得脆弱的一件事就是电池没电了,电源线很容易从后面拉出来。
I recently received a non-pieceofcrapuous laptop, and I am in the process of copying everything from old to new. I'm trying to xcopy c:*.* from the old machine to an external hard drive, but because the cord pulls out so frequently, the xcopy is interrupted fairly often.
我最近收到了一台非便携式笔记本电脑,我正在复制从旧到新的所有内容。我正在尝试从旧机器到外部硬盘驱动器xcopy c:*。*,但由于线缆频繁拉出,xcopy经常被中断。
What I need is a switch in XCopy that will copy eveything except for files that already exist in the destination folder -- the exact opposite of the behavior of the /U switch.
我需要的是XCopy中的一个开关,它将复制除目标文件夹中已存在的文件之外的其他内容 - 与/ U开关的行为完全相反。
Does anyone know of a way to do this?
有谁知道这样做的方法?

/D may be what you are looking for. I find it works quite fast for backing-up as existing files are not copied.
/ D可能正是您要找的。我发现备份工作速度非常快,因为不会复制现有文件。
xcopy "O:\*.*" N:\Whatever /C /D /S /H
/C Continues copying even if errors occur.
/D:m-d-y Copies files changed on or after the specified date.
If no date is given, copies only those files whose source time
is newer than the destination time.
/S Copies directories and subdirectories except empty ones.
/H Copies hidden and system files also.

I find RoboCopy is a good alternative to xcopy. It supports high latency connections much better and supports resuming a copy.
我发现RoboCopy是xcopy的一个很好的替代品。它更好地支持高延迟连接,并支持恢复副本。

It was not clear if you only wanted a command line tool, but Microsoft's free SyncToy program is great for maintaining a replication between a pair of volumes. It supports pushing changes in either or both directions. That is, it support several different types of replication modes.
目前尚不清楚你是否只想要一个命令行工具,但微软的免费SyncToy程序非常适合维护一对卷之间的复制。它支持在任一方向或两个方向上推动更改。也就是说,它支持几种不同类型的复制模式。

I would suggest using rsync, several ports are available, but cwrsync seems to work nicely on Windows.
我建议使用rsync,有几个端口可用,但cwrsync似乎在Windows上运行良好。
