Robocopy One-Way Sync

I think my command is wrong.

I only want to do a oneway sync from c:\SmarterMail\Domains tp \\My.IP.Add.Ress\C$\SmarterMail\Domains

My current command is this:

robocopy /E /S /MIR /Z /W:1 /R:1 /MIR \\My.IP.Add.Ress\C$\SmarterMail\Domains C:\SmarterMail\Domains

But... the more I read, it looks like this may be a two-way mirroring? What command do I need just to do the one-way sync?

Solution 1:

As per the documentation the syntax is as follows:

robocopy <Source> <Destination> [<File>[ ...]] [<Options>]

There's a few oddities with your script:

1. /S copies subdirectories (but not empty ones) /E copies subdirectories including empty ones. /E implies /S so you can drop the /S
2. However /Mir is described thusly "Mirrors a directory tree (equivalent to /e plus /purge)" So you can drop both the /E and the /S
3. You've included the /Mir option twice? Unnecessary
4. Main Issue - you've got the source and destination the wrong way round...

So the command should be

robocopy /MIR /Z /W:1 /R:1 C:\SmarterMail\Domains \\My.IP.Add.Ress\C$\SmarterMail\Domains
