Windows robocopy help




















The default value of n is 1,, one million retries. Specifies the wait time between retries, in seconds. The default value of n is 30 wait time 30 seconds. Specifies that the progress of the copying operation the number of files or directories copied so far will not be displayed. Writes the status output to the log file as Unicode text appends the output to the existing log file. No files were copied. No failure was encountered. No files were mismatched. The files already exist in the destination directory; therefore, the copy operation was skipped.

There are some additional files in the destination directory that are not present in the source directory. Additional files and mismatched files exist. No files were copied and no failures were encountered. This means that the files already exist in the destination directory. These old-fashioned methods are not only time-consuming, but can also cause problems, e. Therefore, it's better to transfer files with the file copy program - Robocopy. Robocopy also known as Robust File Copy is a Windows command-line file replication utility.

It functionally replaces Xcopy with more practical options. With more than 80 switches, it owns three main abilities:. Before Windows Vista, Robocopy acted as an individual utility.

It now sits on a high pedestal in the system32 directory on every Windows installation. Robocopy supports multi-threaded mode, that is, you can copy multiple files at the same time with multi-threaded enabled.

Above all, while copying files correctly, it also preserves their original attributes and timestamps. As an extremely versatile program, Rococopy is often used to transfer files over a network. The task is a two-step process. Users should first enable file sharing on the source computer.

Then use the Robocopy in the destination device to transfer files over the network. The specific steps are as follows. Step 4. Select the Everyone group from the drop-down menu. Let me know your findings. This switch has been known to more accurately preserve file timestamps when transferring over a network. This is also known as the inter-packet gap option. This option defines in milliseconds the frequency in which robocopy will wait between sending new packets.

A reader on Reddit discovered the hard way to not use mapped drives as a destination directory. Instead, always use always use a UNC path. You might run into issues with the character limit if you do. Check out this Microsoft doc for more information. The copied files will not be readable and will generate errors when trying to manipulate them. Serverfault link with more info. Robocopy uses backup mode to use the SeBackupPrivilege for reading files and the SeRestorePrivilege user right to access any files it needs.

This ignores any ACEs that would normally prevent you from accessing those files. The SeBackupPrivilege and SeRestorePrivilege user rights are normally assigned to users in the Backup Operators and Administrators groups but sometimes they can get removed. Backup module eliminates that risk and temporarily grants the user executing robocopy those rights. The large majority of the options available to you are to exclude files and directories many different ways.

You can use a wildcard to filter on files matching a specific file name string or extension. Y0u can also provide multiple sets of file name matches by separating them with a space as shown below. Robocopy allows you to filter items not just by file but by directory name too. Below you will find all of the robocopy options that will exclude files and folders based on various timestamp attributes.

You have seen that dozens of options are available to you. Thankfully, you have a better option than memorizing and ensuring all of these options are spot on every time. Robocopy job files are text files containing one option per line. Once created, you can then either use robocopy to modify them or a simple text editor. A typical job file created with robocopy has an RCJ extension and looks like the below snippet.

You can see that you can provide comments in the job file using :: which is most of what this file has. Also, note that even if an existing job file already exists, robocopy will always overwrite the existing one. Backup or version control your job files! Let me know if you were able to get this to be included.

Robocopy reads all of the parameters inside of the job file. It then executes just as if you provided the options directly on the command-line. However, it would be better explained as creating a job file without running a job. Since job files are just text files, you could edit them with your favorite text editor or you could have robocopy do it for you. You can add the new option like below:.

You can even combine the use of job files too. When specifying multiple job files in the same run, all of the options used in that run will be combined together.

In that mode, robocopy will pause whenever a file copy would cause the destination volume's free space to go below a 'floor' value, which can be explicitly specified by the LFSM:n[KMG] form of the flag. In this first example, any. Whenever you want to copy one or more files and not a complete directory the file must be specified after the destination directory. In the above example, the robocopy command would copy all files not directories in the hope directory to the hope2 directory.

In the above example, all files and folders including empty ones are copied from the hope directory to the hope2 directory. Next, this example would copy any of the files in the hope directory on the network computer named computer to the current computer hope2 directory.
