This thread is locked This hotfix contains Fixes an issue in which the Robocopy. This issue occurs when the file names Until Vista, Robocopy was a part of AzCopy vs.

AzCopy and RoboCopy are two fundamentally different file copy tools. RoboCopy uses any version of the SMB protocol. This causes hidden files to be copied. This issue occurs in It is intended for consistent copying or mirroring of directories wherever the computer has Assume that you use the following robocopy command to perform file replication on a computer that is running Windows 7 or Windows Server R2: robocopy You may need to add one more command to copy the permission Install the most recent version of Robocopy on the server that you will use to copy the files — either the source server or the destination server; you will need to install the most recent version for the operating system version.

For instructions, see Step 2: Stabilize files that will be replicated. Unless you are preseeding files from a server running Windows Server R2, you can run Robocopy on either the source or destination server. The destination server, which typically has the more recent operating system version, gives you access to the most recent version of Robocopy.

Ensure that sufficient storage space is available on the destination drive. Do not create a folder on the path that you plan to copy to: Robocopy must create the root folder. When you decide how much space to allocate for the preseeded files, consider expected data growth over time and storage requirements for DFS Replication. On the source server, optionally install Process Monitor or Process Explorer, which you can use to check for applications that are locking files.

For download information, see Process Monitor v3. Before you use Robocopy to preseed files, you should download and install the latest version of Robocopy. This ensures that DFS Replication does not skip files because of issues within the shipping versions of Robocopy.

The source for the latest compatible Robocopy version depends on the version of Windows Server that is running on the server. For information about downloading the hotfix with the most recent version of Robocopy for Windows Server R2 or Windows Server , see article in the Microsoft Knowledge Base.

Alternatively, you can locate and install the latest hotfix for an operating system by taking the following steps. After you install the latest version of Robocopy on the server, you should minimize the chances that locked files will block copying by using methods in the following table. Most applications do not exclusively lock files. However, during normal operations, a small percentage of files might be locked on file servers. Employees connect to a standard file server and edit documents, multimedia content, or other files.

Sometimes referred to as the traditional home folder or shared data workloads. Only perform Robocopy operations during off-peak, non-business hours. This minimizes the number of files that Robocopy must skip during preseeding. If you set permissions for a common group such as Everyone or Authenticated Users to READ, standard users might be less likely to open files with exclusive locks if their applications detect the Read-only access when files are opened.

You might also consider setting a temporary firewall rule for SMB port inbound to that server to block access to files or use the Block-SmbShareAccess cmdlet. However, both of these methods are very disruptive to user operations. Temporarily disable or uninstall the applications that are locking files. You can use Process Monitor or Process Explorer to determine which applications are locking files. To download Process Monitor, open Process Monitor v3.

After you minimize locks on the files that will be replicated, you are ready to preseed the files from the source server to the destination server. You can run Robocopy on either the source computer or the destination computer. The following procedure describes running Robocopy on the destination server, which typically is running a more recent operating system, to take advantage of any additional Robocopy capabilities that the more recent operating system might provide.

Log on to the destination server with an account that is a member of the local Administrators group on both the source server and the destination server. To preseed the files from the source to destination server, run the following command, substituting your own source, destination, and log file paths:.
