Zentyal Share as time machine destination / custom samba share parameters

[DoerrSt2]

Hi,

I've just installed Zentyal 6 and it works fine so far.

Now I tried to use a samba share as a Destination for Apple TimeMachine backups. To archieve that a share is automatically detected I have to add some parameters to the samba share in the configuration file:

    vfs objects = catia fruit streams_xattr
    fruit:aapl = yes
    fruit:time machine = yes

Changing the file works fine but my changes are overwritten if I change the share. Is there any way to configure this additional parameters?

Thanks!
