nsd.conf(5) has this:
zonefiles-write: <seconds>
Write changed secondary zones to their zonefile every N seconds.
If the zone (pattern) configuration has "" zonefile, it is not
written. Zones that have received zone transfer updates are
written to their zonefile. Default is 0 (disabled) when there
is a database, and 3600 (1 hour) when database is "". The
database also commits zone transfer contents. You can configure
it away from the default by putting the config statement for
zonefiles-write: after the database: statement in the config
file.
Default is to have no database, so on a slave it takes an hour to write to disk.

I'm not entirely sure you are real.
