3.10 Backup and Disaster Prevention

Snapshotting is the preferred method for backing up cloud system VM instances. Once the DSR and optional sub-systems are installed and configured, before adding traffic, use the appropriate cloud tool (VMware Manager or the OpenStack Horizon GUI) to take snapshots of critical VM instances. It is important to snapshot the control instances, such as the NOAM and SOAM.

Note:

It is recommended to follow this procedure to back up the NOAM and SOAM database.

1. 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 or Controller
   • SDS NOAM
2. To login, in NOAM VIP, establish a GUI session as the guiadmin user on the NOAM.
   
   

   

   
   
3. To backup configuration data for the system, in NOAM VIP, perform the following steps:
   1. Navigate to Status & Manage, and select Database.
      
      
      
      
   2. Select the active NOAM server and click Backup.
      
      
      
      
   3. Ensure Configuration checkbox is marked.
      
      
      
      
   4. Enter a filename for the backup and click OK.
4. To verify the backup file existence, in NOAM VIP, perform the following steps:
   1. Navigate to Status & Manage, and select Files.
      
      
      
      
   2. Select the active NOAM tab.
      
      
      
      

      The files on this server are displayed.

   3. Verify the existence of the backup file.
5. To download the file to a local machine, in NOAM VIP, perform the following steps:
   1. Select the backup file.
   2. Click Download.
      
      
      
      
   3. Select OK to confirm the download.
      
      
      
      
6. Upload the image to secure location.
   Save the backed-up image to a secure location where the system administrator can fetch server backup files while performing disaster recovery.
