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.
More specifically, with multi-threaded capabilities, Robocopy can simultaneously copy multiple files in parallel, which will result in very fast backup operations. I'm using 32 threads in my example, as I found it to be a good starting point. Like all command-line tools, Robocopy keeps you apprised of the status of operation right in the Command Prompt window. However, you'll probably want to customize and record that feedback in a log file.
Now, my command is:. Now that you know how the script works and which switches are necessary, you can launch Notepad, type the command, and save the file as RobocopyBackup.
You'll find the log file in the same directory as the script after each backup operation. Keep in mind that while the log file is a simple text file, it can be larger than Notepad can handle. As such, you may want to use Wordpad or another word processor to open and view the log file. Now, whenever you want to make an extra backup, you can just double-click on RobocopyBackup.
When it is done, you can examine the Backup. 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. 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. The features included with Robocopy allow you to copy files very quickly but remember that you will need a wired connection for the best experience.
The time to complete the transfer will depend on the network connection speed and drive performance. This is a two-step process. You must first configure file sharing on the source device and then use Robocopy in the destination device to perform the transfer. Use the drop-down menu to select the user or group to share files or folders — For example, the Everyone group. For example, you can select Read default if you only want users to view and open files. Note the network path for the folder that other users will need to access the content over the network, and click the Done button.
After you complete the steps, make a note of the folder path and the IP address of your source computer. Once file sharing is configured on the source device, you can copy the files using Robocopy from the destination device. Search for Command Prompt , right-click the top result, and select the Run as administrator option. In the above command, make sure to change the source and destination paths with your configuration.
