Proper backup of all NSX components is crucial to restore the system to its working state in the event of a failure.
The NSX Manager backup contains all of the NSX configuration, including controllers, logical switching and routing entities, security, firewall rules, and everything else that you configure within the NSX Manager interface or API.
Depending on whether the NSX Manager is for management domain or workload domain, the scheduled backup is auto-configured during bring-up or workload domain deployment. The backup data is saved in the SDDC Manager Utility VM, which is in turn backed up using your chosen backup appliance.
Because the NSX Manager backup is auto-configured, do not modify the backup configuration settings in the NSX Manager interface, or the NSX Manager backup will not be included in the Cloud Foundation process.
Additionally, you can trigger NSX Manager backups on demand directly in the NSX Manager appliance interface.
