Samba Replication

I Was able to replicate samba users/profiles from one CDS Server to another(Backup server).
My question is do i need to do this every time when a new user is added or deleted so that profiles/users remain exactly the same on both primary and secondary servers.Is there any possibility to do this task automatically on a daily basis.
So that my Primary or main server can replicate the profiles to secondary server on a daily basis.
