Hi, I might have missed something, but how can I create a fail-safe backup procedure? We've got Samba 2.2.0 release (using it since alpha1) running fine, doing PDC functionality for Win9x, NT, AND Windows2000 (SP1). Is it enough to backup: smb.conf, /etc/smbpasswd, /etc/MACHINE.SID, /etc/passwd ? Any other? It seems normal to me that, in case of a system crash, we preserve the 'original' domain name and ("PDC") computer name to install on.. Greetings, Kristof.
