Explanation

The zone database files are the zones' permanent storage location, holding all the zones' resource records. If you use DNS Manager to make a change to a zone, the copy of the zone in the name server's memory is changed, and a flag is set to update that zone's database file. The name server updates the zone database file when it exits, unless you tell it to update it sooner. The command DNS --> Update Server Data Files causes the name server to update the zone database files of all zones it's a primary for, regardless of whether or not they've been modified. To avoid losing data, we recommend using DNS --> Update Server Data Files after any changes- use it like you use the Save command in other applications.
