1. C:\windows\system32\robocopy.exe C:/Data E:/Backup /MIR /SEC

You clone the folder structure retaining the permissions and audit data, if you have them.
(Note, the switch /MIR delete files from destination folder, if they don’t longer exist in the source folder!)

2. C:\windows\system32\robocopy.exe “D:\doc” “F:\xarabas” /mir /np /log:c:\log.txt

You clone the “doc” folder structure, you don’t display % copied (/np option).
At the end the robocopy will create a log file on c:\log.txt

3. C:\windows\system32\robocopy.exe \\\share\path \\\share\path /MIR

You clone the shared folder from source server ( to a shared folder in a destination server (

    People should note that Robocopy is very sensitive about the time stamp. It’s best if copying to a server that you use GPO to make sure the time is synced up.

    Buenos dias, pregunta concreta, Robocopy me sirve para clonar permisos SHARED o NO, ya que ni aun pasando la llave de registro LANMANSERVER\SHARED funciona
