XO - This excludes older files/folders if the destination file/folder exists and is the same date R:2 - This specifies the number of retries on failed copies. W:1 - This specifies to wait 1 second between retries when copying files. If access is denied, it will try to copy in backup mode. If a file is in use, it will retry after a set amount of time. ZB - This uses restartable mode when copying files. COPYALL - This will copy all of the NTFS permissions and attributes (security permissions, timestamps, owner info.) MIR - This will copy all files and subfolders, and it will remove files/folders from the destination, if they no longer exist on the source. The + sign tells it to append the log file, instead of overwriteing it. LOG+c:\robolog.txt - This tells the command where to write the logs. TEE - This will display the output of the command in the console window, and it will write it to a log for further review. Make sure to put them in quotes if the contain spaces. Robocopy source destination - source and destination can be a local path (C:\Users\MyAccount), a mapped drive (U:\sharedfiles), or a UNC path (\\server01\share\data). Now, let's break down the command so we can know exactly what each switch does: All of the files that haven't been modified are skipped. Also, the newly added file to the source is copied to the destination. The file that was deleted from the source, is also deleted from the destination. See what happens when I run the command again: Now I'm going to delete a file from the source, and then add a different file to the source.

In the image below, you see a source and destination directory. (Make sure to launch the command prompt as administrator) Robocopy C:\source C:\dest /TEE /LOG+:c:\robolog.txt /MIR /copyall /zb /w:1 /r:2 /xoįirst, I'll show you examples of this command in action, and then I'll break the command down to show you what each part does. You can run the command once to copy the bulk amount of the data, then you can run it again later, and it will only copy changed files, which will make it much faster. This command will also keep all of the NTFS permissions and file attributes.Ī typical use scenario for this command is copying a large file share.
