In Nebula version 19.20, the Backup & Restore feature has been completely redesigned and promoted to an independent menu item in the NCC interface. This update enhances visibility, provides greater administrative control, and introduces automation options for backing up and restoring configuration data across sites, switches, and firewalls.
Overview and Key Enhancements
| Feature | Description |
|---|---|
| Independent Menu Item | Backup & Restore now appears as a separate option in the Nebula navigation menu. |
| Two Backup Types | Supports both Site Backup & Restore and Switch Backup & Restore. |
| Scheduled Backups | Adds automation options for daily, weekly, or monthly backups. |
| Improved Summary Tables | Shows detailed backup status, timestamps, and administrator information. |
Site Restore Rules
| Rule | Description |
|---|---|
| Site-to-Same-Site | A backup from Site A can only be restored to Site A. |
| Device-Based Rule | The backup is bound to each device’s MAC address. Restoration works only on the same device, not a replacement. |
| Cross-Site Restore | Not supported. |
Purpose: Used for configuration rollback or recovery from faulty settings.
Cloud-Managed Firewall — Backup & Restore Scenarios
| Scenario | Result |
|---|---|
| Same model | Restoration succeeds and restores full configuration. |
| Smaller → Larger model | Restores successfully; null values for missing features not available in the smaller model. |
| Larger → Smaller model | No restoration applied; current settings remain unchanged. |
| Different series (e.g. ATP → SCR) | No restoration applied. |
| Newly added firewall (none before restoration) | Restores to default configuration. |

- Each site can store up to two scheduled backups.
Restoration Guidelines
New Features Reset to Default: Features added after the backup revert to default values upon restore.
Example: PoE Schedule settings return to defaults.
Unlisted Devices Remain Unchanged: Devices added after the backup are not modified.
Restore to backed-up status
- Click Actions > Restore.
- Choose the desired backup file.
- Confirm restoration when prompted.
- The system applies the configuration to the same site and devices (MAC-based validation).
