VDU snapshot

A snapshot of a VDU contains its complete configuration and can be used to restore that VDU in case of malfunctions.

You can take snapshots of multiple versions of the VDU, which is especially useful in the early stages of deployment and testing. If an update or modification causes problems, you can revert to the latest stable version using the corresponding snapshot. In this way, snapshots let you isolate errors and implement version control.

You can also use snapshots to scale your VDU by deploying multiple identical instances.

To take a snapshot of the VDU:

1. In the menu, go to the Catalog section.

   The network service management page is displayed.

2. In the Network services panel, select a network service.

   The graphical design tool with the network service topology is displayed.

3. Click the VNF.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand button .

   By default, the Flavours tab is selected, which displays the flavours of virtual machines for the network function. Flavours are described in the VNF package.

4. Select the VDU management tab.

   A table of VDUs is displayed.

5. Click Management next to the VDU and in the drop-down list, select Snapshot.

   This opens a window with a table of snapshots.

6. In the Name field, enter the name of the snapshot.
7. In the Description field, enter a brief description of the snapshot.
8. Click Create.

The snapshot is created and displayed in the table.
