File Based Incremental Conversions fail with the error "An entry with the same key already exists"

This article discusses an issue which may occur when trying to perform a File-based incremental synchronization. When running a file based conversion the job will fail at "Source Machine Ready to Send Files" with the error "An entry with the same key already exists"

During a file based incremental conversion you may receive the above error when Microsoft Windows Services for UNIX or Subsystem for UNIX-based Application (SUA) is installed by using the "Change the default behavior to case sensitive" option. When this option is enabled, the installation creates a "pod" symbolic link under the same directory as the Pod directory. PlateSpin cannot identify case-sensitive file names on windows based systems.

On every volume on the source system, there is a file called PlateSpinCatalog.dat. Open this file using a text editor, and search for "SFU\usr\local\lib\perl5\5.6.1\Pod". You will find something similar to what is listed below.

SFU\usr\local\lib\perl5\5.6.1\Pod
