6.3 Backups and Disaster Prevention

This procedure provides information on backups and disaster prevention.
Prerequisites:

DSR and optional sub-systems are installed configured.

  1. Backup from VIM.
    The preferred method of backing up cloud system VM instances is by snapshotting. Once the DSR and optional sub-systems are installed and configured, but before adding traffic, use the appropriate cloud tool such as the VMware Manager or the OpenStack Horizon GUI, to take snapshots of critical VM instances. It is particularly important to snapshot the control instances, such as the NOAM and SOAM.

    Note:

    Perform the following steps also to back up the NOAM and SOAM database.
  2. Identify Backup Server.
    Identify an external server to be used as a backup server for the following steps. The server should not be co-located with any of the following items:
    • Cloud Infrastructure Manager Server/Controller
    • DSR NOAM
    • DSR SOAM
  3. Log in to NOAM/SOAM VIP.
    1. Establish a GUI session on the NOAM or SOAM server by using the VIP IP address of the NOAM or SOAM server.
    2. Open the web browser and enter a URL http://<Primary_NOAM/SOAM_VIP_IP_Address>
    3. Login as the guiadmin user.
  4. In NOAM/SOAM VIP, perform backup configuration data for the system.
    1. Navigate to Main Menu, and then Status & Manage, and then Database.
    2. Select the active NOAM server and click Backup.
    3. Ensure the Configuration checkbox is marked.
      Configuration

    4. Enter a filename for the backup and click OK.
  5. In NOAM/SOAM VIP, verify the backup file existence.
    1. Navigate to Main Menu, and then Status & Manage, and then Files.
    2. Select the active NOAM or SOAM tab.

      The files on this server are displayed.

    3. Verify the existence of the backup file.
  6. In NOAM/SOAM VIP, download the file to a local machine.
    1. From the previous step, select the backup file.
    2. Click Download.
    3. Click OK.

    Note:

    • Transfer the backed up image to a secure location identified in step 2 where the server backup files are fetched in case of system disaster recovery.
    • Repeat Steps 3 through 6 to back up the active SOAM.
