If DS-Client detects a placeholder / stub is created on the source, the corresponding file on DS-System will be deleted, based on the specified conditions. |

| Keep all placeholders / stubs •	All placeholders or stubs will be kept on DS-System, as well as any full file generations that appear after that latest placeholder/stub. |
