Symptoms

Assume that you use the following robocopy command to perform file replication on a computer that is running Windows 7 or Windows Server 2008 R2:

robocopy <Source> <Destination> /sec /mirHowever, the Discretionary Access Control Lists (DACLs) for the files are updated incorrectly. This issue occurs even if the DACLs in the source location and in the destination location are the same.

Note When this issue occurs in a network environment that uses the Distributed File System Replication (DFSR) service, a very large DFS replication backlog is generated.

Resolution

Hotfix information

Note If you use the robocopy command to perform file replication between two computers, you must install this hotfix on both computers.

Note After the update is installed, the robocopy command behavior is changed. When you copy security descriptors, destination files don't inherit permissions from new parent even when the inheritance is set..
