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. For example, perhaps you have a large list of files to exclude from your backupfiles copy job. Open up a text editor, and add the following to create an exclude. Robocopy combines all options into one. Robocopy allows you to pass values from the command-line to jobs when they are run.
For a simple example, create a job file with no source or destination using the syntax below. By default, robocopy only processes one file at a time. The maximum is I suggest starting at 32 to see how your computer and network handle things and adjust the threads accordingly. This is great if you have a maintenance window or a time when everyone has gone home for the day. For example, to invoke robocopy but only allow it to run between the hours of 5PM and 9AM as defined by the system clock, run:.
You must ensure that both times are in a hour format and are exactly four digits long. The window must be greater than two minutes.
Robocopy will always return an output log. You can include either of these options or both of them together. The only output you will receive on the console is the path to the log file. This option causes robocopy to write the output to the log file while still maintaining the default behavior of returning output to the console. Like all other command-line utilities, robocopy returns exit codes depending on the results of the execution.
Below you will find all of the exit code that robocopy returns and their explanation. Any exit code greater than seven indicates at least one failure during execution.
To prevent this, you can change the exit code to 0 if it returns 1. This code excludes extras that will prevent any deletions from the destination. If it returns 1 then use the exit keyword to exit the script with 0. You can then check the ExitCode property for a value of 1. The robocopy invalid parameter 3 error is the most common, it seems. You can build your own strings of robocopy or you can take what others have learned and use them!

We then add an explicit ACE for the Administrators group for full control on every object recursively even though we are also setting inheritance. Finally, we do a full robocopy copy with DACLs to the destination with log. Log can then be reviewed for additional permission issues or just file locks and another delta sync can be performed later.
Recursively force Administrators group as the owner of all files and directories. The basic command line syntax for Robocopy is similar to the syntax used for the familiar Xcopy command line application popular in DOS, so many years ago. The basic Robocopy command line will follow this general pattern:. You'll of course substitute the names and paths with your own. My basic command begins with:. Now, I want to back up every folder in the source, even any empty folders, as they may be placeholders for future data.
I also don't want to have files on the backup that I deleted from my hard disk. My command is now:. Windows 10 uses junction points to link various operating system folders to the user profile folder.
For example, the Cookies folder and the SendTo folder are linked to the user profile folder via junction points. One of Robocopy's most handy features comes into play when it encounters a file that is in use. When it does, Robocopy will stop and wait for that file to be closed so that it can continue with the copy operation.
It will retry to copy the file every 30 seconds. The default number of retries is 1 million no joke! As this will most likely prevent the backup operation from ever completing, you should reset it to a reasonable number. I chose five retries with a second wait time. That way, after a reasonable number of retries and wait period, Robocopy will move on. At this point, I am ready to add the multi-threaded switch, which enables Robocopy to perform a multi-threaded copy option.
Excluding extra files will not delete files from the destination. Excludes "lonely" files and directories present in the source but not the destination. Excluding lonely files prevents any new files from being added to the destination. Includes "tweaked" files.
Tweaked files have the same name, size, and times, but different attributes. Specifies the minimum last access date excludes files used since n If n is less than , n specifies the number of days. Specifies the number of retries on failed copies. 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. Care must be taken when using Robocopy command-line, as you have no chance to step back.
Besides, some users find Robocopy not copying files during the operation. To transfers files easily and efficiently, you might require a Robocopy alternative. This freeware is designed with a user-friendly GUI, which makes it easier to operate than Robocopy. Open files can also be copied without effort. Except for copying multiple files simultaneously, tasks can also be schedule backup daily, weekly or monthly.
Additionally, you can enable email notification to see if your operation is completed successfully. Other practical features like system backup , disk backup, partition backup, file backup and disk clone can help you manage data flexibly.
So go download this freeware and get started! This article gives a detailed introduction to Robocopy in Windows Although this program can be used to transfer files over a network, it involves a complicated and time consuming process.
By the way, after upgrading to advanced editions , you can enjoy more useful features, for instance, real-time sync.
