Question about Retention


I am using Vembu Bdr backup for my Vmware infrastructure. I am running a daily incremental backup plan with basic retention and keep last 5 daily merged recovery points. I am notice that the backup storage always increased and all incremental backup stored and not deleted after 5 days. The result is after some day the backup pool running out of space and backup plan stops.

I want to make a plan that keep only the last 5 days and not storage only growing up. Is it something that I made wrong with the plan or have I understand wrong how the retention works?

Kind Regards
