Hi all. I have a massive file copy I need to do as I'm moving data from fileserver1 to fileserver2. There's so much data, and it copies so slowly, that it will take possibly as long as 24 hours for the robocopy to complete. Also, there's no way to keep the users out of the files while the copy is going on.

Because of this I was wondering how I could use robocopy to get the job done. If I use the /MIR switch I know it will create an exact copy of what's in fileserver1 and place it on fileserver2. Once that's done I'd like to run another robocopy that only copies files that have changed since the last copy. I'd like to think that would result in a copy that would go very quickly. The only problem is I don't know how to do that.

Can robocopy do that? If so, how?

Why do you want to do this? Depending on your setup and reason, but it might be easier to just use DFS to replicate the data to the file servers. Then you can either remove the original file server, or leave it for redundancy. That way you get to ignore certain concerns, like locked files.

✔ Best Answer
Robocopy is intelligent and only copies files that differ. So you just need to run the same command again. You might want to use a command line like:

robocopy \\SourceServer\Share \\DestinationServer\Share /MIR /FFT /Z /W:5

to allow for locked files.
