Clean Up On NAS Drive?

I have my full file backups to min=1 and max=2
same for incremental backups Min=1 max=2

In the backup logs I see its backing up all the changes which occur :-) YAY

BUT what I do not see happening is a cleanup…Meaning that I have over 30 incremental data folders taking up space and if i understand the settings correctly it should be 2 incremental data folders…

NOTE: For a diagnoses under settings I set the Cleanup time to be for 10hrs a day
