To download the extension

1. Sign in to the NetBackup Web UI.
2. From the left navigation pane, click Cloud and then select the NetBackup Snapshot Manager tab.

   All the NetBackup Snapshot Manager servers that are registered with the primary server are displayed in this pane.

3. From the desired NetBackup Snapshot Manager row, click the actions icon on the right and then select Add extension.

   Note:

   For the VM-based extension you do not need to download the extension. Proceed directly to steps 7 and 8 to copy the token.

4. If you are installing the extension on a managed Kubernetes cluster, then on the Add extension dialog box, click the download hyperlink.

   This launches a new web browser tab.

   Do not close the Add extension dialog box yet. When you configure the extension, you will return to this dialog box to generate the validation token.

5. Switch to the new browser tab that opened and from the Add extension card, click Download. The extension file nbu_flexsnap_extension.tar will be downloaded.
6. Copy the downloaded file to the NetBackup Snapshot Manager host, and untar it by running the tar -xvf nbu_flexsnap_extension.tar command .

7. Then to generate the validation token, on the Add extension dialog box, click Create Token
8. Click Copy Token to copy the displayed token. Then provide it on the command prompt while configuring the extension.

   Note:

   The token is valid for 180 seconds only. If you do not use the token within that time frame, generate a new token.
