oracle backup using DDboost plugin

We have configured oracle backups using ddboost plugin on oracle servers. Weekly data backup is around 30 TB. There is no backup server\backup software involved. It is configured as per technical documentation shared by EMC. Backup throughput is excellent. Issue is scripts running on oracle server clears data sets\backup sets at their end, How about auto cleaning on data domain. DDbboost plugin stores oracle datasets on a MTREE \oracle-only. 

DDboost backups are fast but how cleaning will be setup on data domain. DD9800 version 5.4
