I was under the impression if I set this config in my general config it'll delete my db sql dumps in my storage folder when i hit my limit. I set it to two to test and did a few backups and I already have 5 with the older ones still there. Just wanted to see if that is the purpose of this config? And if not is there a built in way for craft to remove sql backup files in the storage folder older than 'x' days?
