I assume of course you mean the zone in a Samba AD DC, not a simple
This has happened, and yes, I do think we should prevent it at the
database level, as nobody ever really means to do that. Last time that
happened we helped a client jury-rig up a backup of the sam.ldb into
BIND9-DLZ (so only DNS used the old data), allowing service to somewhat
continue while things were fixed back up.
However, I'm sorry to say it won't just be regenerated, while Samba
will try and re-register itself every now and then, I wouldn't count on
it getting back the way you found it fast.
How are your backups?
