用于在远程共享之间复制文件的 SMB 协议 [英] SMB protocol for copying files between remote shares
问题描述
我需要从远程共享\s1复制大量数据到共享\s2.我正在使用 robocopy，它使用 SMB 协议来复制文件.我的问题 - 该协议是否允许直接将数据从 S1 复制到 S2，还是所有数据都必须通过运行 robocopy 的机器?
I need to copy a lot of data from remote share \s1 to share \s2. I'm using robocopy, which uses SMB protocol to copy files. My question -- does the protocol allow to copy data from S1 to S2 directly or all data has to go through the machine on which robocopy is running?
推荐答案
它使用运行它的机器.它从内存中的源复制数据(在当前机器上 - 当前)，然后从那里复制到目标.没有其他方法(好吧，可能有一个客户端/服务器在 source/target 上运行，并且可以远程配置客户端以直接打开到服务器的隧道，并且传输文件 - 但这里不是这样).
It uses the machine that it's running on. It copies the data from source in memory (on the current machine - current) and from there to target. There's no other way (well there could be a client/server running on source/target and the client is able to be configured remotely to open a tunnel directly to the server and transfer the files - but that's not the case here).
您可以尝试robocopy一个大文件从源到目标并使用任务管理器来检查这一点> 监控网络流量:
You can check this out by trying to robocopy a large file from source to target and using Task Manager monitor the network traffic on:
- current - 传入 + 传出
- 来源 - 传出
- 目标 - 传入
- current - incoming + outgoing
- source - outgoing
- target - incoming
并查看以下任何匹配项(如预期):
and see that any of the following match (as expected):
- source - 传出 = target - 传入
- source - outgoing = target - incoming
还有这些(current 发挥作用的地方):
but also these ones (where current comes into play):
- source - 传出 = current - 传入
- current - 传出 = target - 传入
- source - outgoing = current - incoming
- current - outgoing = target - incoming
要直接robocopy(或任何其他文件传输工具)必须在源或目标上运行.
To do it directly robocopy (or any other file transfer tool) must run on either source or target.
