SMB mounted drive and disabled symlinks not cleaning up

Hi,

I have urbackup working with a CIFS mounted, as you know CIFS doesnt support symlinks so I desactivated this option on settings.

Im only using file transfers on clients, making an incremental 5 times in a day.

The problem is… the creation of LOTS of folders from the same client and they are not automaticly being deleted.

for example this is a client folder on server of backed up:

As you can see, those are folders created in every incremental execution and all of them are using the same space.

I just want keep 2 last incremental folders.

In settings this is my configuration.

Maximal number of incremental file backups: 2
Minimal number of incremental file backups: 2
Maximal number of full file backups: 2
Minimal number of full file backups: 2

Thanks you in advance.
