Procedure 2: Restoring from backup standard primary zone 1. Build and configure a stand-alone Windows Server 2003 server with hardware configuration as close as possible to that of the production server. 2. Ensure that the server is not connected to the production network. (Many organizations maintain a standing DR lab environment that has been isolated from the networks it supports.) 3. Restore the system state for a stand-alone Windows Server 2003 server or perform the tasks necessary for a normal Active Directory restore if the server is a domain controller. 4. Restore the DNS zone that were backed up in "Task: Create DNS backup and pull backup files to remote storage.” 5. Validate restore by testing DNS functionality. the restored service is in a DR lab environment, the server may not retain full functionality. Where functionality is not testable, check the configuration items—such as the forwarder IP addresses—against production DNS servers. Dependencies Scheduled zone file and system state backups are being performed. Technology Required DR lab or similar equipment ● Backup ● Storage Management Operations Role Cluster Weekly Operating Quadrant SMF Process: Storage resource management Description Storage resource management (SRM) is a key storage management activity focused on ensuring that important storage devices, such as disks, are formatted and installed with appropriate DNS systems. In addition, SRM includes using management technologies to monitor storage resources to ensure that they meet availability, capacity, and performance requirements. Task: Monitor disk space for DNS logs and database Purpose This task ensures that the DNS zone files can grow as appropriate. Because of the relatively small size of zone files, DNS server disk space is normally not an issue. DNS debug logging is disk-resource intensive. Before enabling and configuring DNS debug logging, review disk availability.
