If a domain zone file was edited manually or changes were not saved in Parallels Business Automation - Standard database, it is possible to restore its configuration to the one that was saved in the Parallels Business Automation - Standard database before. In this case, you can either use a default DNS template or just restore a zone file from the database.
To use a default DNS template for zone files restoring, set this in Domain Manager - Setup. The default DNS template set for a particular hosting plan type is used for restore.
Note: Zone file restoring does not recovers the existing resource records configuration. It only allows restoring records by parsing a corresponding DNS template.
To restore a domain zone file, go to the Service Director - Domain Manager - Domains, select a domain and click the Restore DNS Zone from DB button.
