maintain latest X backup(s) only

maintain latest X backup(s) only

I have installed Password Manager with an SQL database as the back end.  

I've noticed that this changes the "Database Backup" screen;  I can set when the backup runs and the destination but there is no longer a "maintain latest X backup(s) only".  

Is this a bug or is there no way to automatically set when backups get recycled?  How are we supposed to manage these?

Thanks
