Using robocopy to sync folders5/30/2023 On the source server, optionally install Process Monitor or Process Explorer, which you can use to check for applications that are locking files. For planning help, see Edit the Quota Size of the Staging Folder and Conflict and Deleted Folder in Managing DFS Replication. ![]() When you decide how much space to allocate for the pre-seeded files, consider expected data growth over time and storage requirements for DFS Replication. Do not create a folder on the path that you plan to copy to: Robocopy must create the root folder. The destination server, which typically has the more recent operating system version, gives you access to the most recent version of Robocopy.Įnsure that sufficient storage space is available on the destination drive. Unless you are pre-seeding files from a server running Windows Server 2003 R2, you can run Robocopy on either the source or destination server. For instructions, see Step 2: Stabilize files that will be replicated. 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. You need an account that's a member of the local Administrators group on both the source and destination servers. Copy the replicated files to the destination server.īecause pre-seeding does not directly involve DFS Replication, you only need to meet the requirements for performing a file copy with Robocopy.Stabilize files that will be replicated.Download and install the latest version of Robocopy.To use Robocopy to pre-seed files for DFS Replication, follow these steps: Always examine the Robocopy logs after pre-seeding to ensure that you understand which files were skipped because of exclusive locks. To minimize lock conflicts, use Robocopy during non-peak hours for your organization. pre-seeding does not require a perfect match between file lists on the source and destination servers, but the more files that do not exist when initial synchronization is performed for DFS Replication, the less effective pre-seeding is. ![]() ![]() If users tend to lock many files for long periods on your file servers, consider using a different pre-seeding method. Robocopy does not copy exclusively locked files. ![]() Later versions include multi-threading and un-buffered I/O support. The utility provides extensive options that include copying security, backup API support, retry capabilities, and logging. The Robocopy (Robust File Copy) command-line utility is included with Windows Server. The Robocopy method is one of several pre-seeding methods for an overview, see Step 1: pre-seed files for DFS Replication. By pre-seeding files before you set up DFS Replication, add a new replication partner, or replace a server, you can speed up initial synchronization and enable cloning of the DFS Replication database in Windows Server 2012 R2. This topic explains how to use the command-line tool, Robocopy.exe, to pre-seed files when setting up replication for Distributed File System (DFS) Replication (also known as DFSR or DFS-R) in Windows Server. Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, Windows Server 2008
