You cannot use the DFSR service to replicate files in a Windows Server 2008 R2-based domain environment

Symptoms

Consider the following scenario:
  • You use the Distributed File System Replication (DFSR) service in a Windows Server 2008 R2-based domain environment.
  • You have a Distributed File System (DFS) replication group in the domain environment.
  • You use the DFSR service to replicate files in the DFS replication group. The sizes of some files are large. For example, the size of a file is 10 gigabytes (GB).
In this scenario, the files that are large cannot be replicated.

Notes 
  • This issue typically occurs when the replication connection is opened and then closed frequently. This is caused by a scheduled replication job or unreliable network connectivity.
  • In the DFSR debug log, there are information that states the partial copy of the replicated file is saved and then dropped. For example, when the issue occurs, the following information is generated in the DFSR debug log:

Cause

This issue occurs because DFSR considers the partial copy of the replicated file as invalid. When a large file cannot be replicated in one session, DFSR saves a partial copy of the replicated file so that the replication process can continue from where it stopped. Given that the partial copy of the file is considered invalid by DFSR, DFSR has to re-start the replication process. However, the replication connection is never opened long enough for the replication process to be completed. Therefore, large files cannot be replicated.
