All NSX Edge configurations (logical routers and edge services gateways) are backed up as part of NSX Manager data backup.

About this task

Taking individual NSX Edge backups is not supported.

If you have an intact NSX Manager configuration, you can recreate an inaccessible or failed Edge appliance VM by redeploying the NSX Edge (click Redeploy NSX Edge () in the vSphere Web Client). See "Redeploy NSX Edge" in the NSX Administration Guide.

Caution:

After restoring an NSX Manager backup, you might need to take additional action to ensure correct operation of NSX Edge appliances.

  • Edge appliances created after last backup are not removed during restore. You must delete the VM manually.

  • Edge appliances deleted after the last backup are not restored unless redeployed.

  • If both the configured and current locations of an NSX Edge appliance saved in the backup no longer exist when the backup is restored, operations such as redeploy, migrate, enable or disable HA will fail. You must edit the appliance configuration and provide valid location information. Use PUT /api/4.0/edges/{edgeId}/appliances to edit the appliance location configuration (resourcePoolId, datastoreId, hostId and vmFolderId as necessary). See "Working With NSX Edge Appliance Configuration" in the NSX API Guide.

If any of the following changes have occurred since the last NSX Manager backup, the restored NSX Manager configuration and the configuration present on the NSX Edge appliance will differ. You must Force Sync the NSX Edge to revert these changes on the appliance and ensure correct operation of the NSX Edge. See "Force Sync NSX Edge with NSX Manager" in the NSX Administration Guide.

  • Changes made via Distributed Firewall for preRules for NSX Edge firewall.

  • Changes in grouping objects membership.

If any of the following changes have occurred since the last NSX Manager backup, the restored NSX Manager configuration and the configuration present on the NSX Edge appliance will differ. You must Redeploy the NSX Edge to revert these changes on the appliance and ensure correct operation of the NSX Edge. See "Redeploy NSX Edge" in the NSX Administration Guide.
