This procedure describes how to restore a backup.

For more information, see the Overview of the backup and restoration.

Note

When restoring a backup, a number of services are automatically restarted/unavailable after the restore is marked as complete

The post-restoration time can be long (10~20 minutes) and during this time, access to the webui displays the message "502 bad gateway".

Important

It is possible to restore a backup on a GCenter with a different IP configuration.
Before performing this operation, all network interfaces present on the source GCenter must be active and configured on the target GCenter.
Example:

The source GCenter has two active interfaces (MGMT0 and VPN0).

Both interfaces must be enabled and configured at the IP level on the target GCenter before performing the restore.

8.4.3.2. Prerequisites

8.4.3.5. Procedure to follow the upgrade and hotfix paths

Astuce

Since the upgrade and hotfix path is not specified in the backup name, it is imperative to set up a tracking of these paths.

To do this, when downloading or exporting the SCP or FTP of the backup:

Create a tree structure indicating the current version of the GCenter (example: 2.5.3.102-XXXX-HFX)
Store the downloaded or exported backup in this folder
Modify the tree structure each time a version is upgraded or a hotfix is applied
Use the backup in the directory of the GCenter version to be restored

8.4.3.5.3. Procedure to restore a backup to another blank GCenter

In the event of a GCenter replacement, it is mandatory to respect these criteria before restoring the backup:

Reinstall the new GCenter along the same upgrade and hotfix path as the old GCenter.
Name the new GCenter in the same way as the old GCenter (same FQDN).
Configure the network section of the new GCenter, allowing access to the WebUi.
Apply the licence to the new GCenter in order to access all the configurations. Until a license is entered, the WebUI is blocked on the license page.

Access the restoration page as described in the previous procedures
Click on the `Parcourir` button (12)
