Despite of defined retention policy to recovery window of 7 days, the auto backups of control file & SP file are not marked as obsolete and are not removed by executing following statement:

DELETE OBSOLETE;

Pl guide.

So does it work for datafiles and arcxhivelogs?
If that is the case and report/delete obsolete is not working only for controlfile/spfiles , it is a known bug.
Check with Oracle support.

There could be a lot we are overlooking.
control_file_record_keep_time / your backups (last full, incremental) etc

Yes, REPORT OBSOLETE is working fine for Datafiles & Archivelog files backups. I'm doing a manual delete of old control file backups folders using DOS script.
