How to use Samba NAS add-on for Timemachine backup onto internal storage

Hi.
I would like to use my HASS for Timemachine backup of my MAC book (running Sonoma).

I have a RPI4 with HassOS image 11.1 with 1TB M.2 SSD SATA disk (internal storage).
I did not define any additional partitions during the HASSOS installation, so default HassOS image install - it reports the 1TB of storage.

Running add-on Samba NAS 12.1.0-nas. I read the documentation and enabled the option “timemachine TRUE”. I can see the default shares and also see a “Timemachine” folder under the share called “share”. I have mounted the “share” but Timemachine report that it can’t see any useable storage.

From my mac I can add and delete files in the Timemachine folder so it does have r/w access to it.

Any ideas why TM won’t use/see the share?

Many thanks
Jesper

It will not work with the Samba Addon because it has to have those “fruits” commands.
I would install a samba server on the host assistant host os

A samba config file which may work

[global]
   fruit:model = MacSamba
   fruit:advertise_fullsync = true
   fruit:aapl = yes

[dell]
    comment = Samba
    path = <mountpoint of your timemachine backup folder>
    valid users = timemachine
    writeable = yes
    kernel oplocks = no
    kernel share modes = no
    posix locking = no
    vfs objects = catia fruit streams_xattr
    ea support = yes
    browseable = yes
    read only = no
    inherit acls = yes
    fruit:time machine = yes
    spotlight = yes

the idea to install a samba server on the host assistant os will only work if your os is self supervised.
