Note: The Backup and Restore functionality is for Configuration Settings only. Analytical Data is not backed up.


Backup NetVisor UNUM Configuration


Select Option 1 to backup your configuration. 


Option 1 - Advanced Settings Backup Configuration - NFS Mount not configured


The Backup and Restore function configuration is dependent on the NetVisor UNUM instance. A standalone NetVisor UNUM instance requires an NFS mounted share.


Note: In a clustered NetVisor UNUM environment data is replicated automatically across the nodes.


If an NFS mounted share is not configured an error message is displayed as shown in the above image.


To configure an NFS share, use the following steps to set up the Backup and Restore function.


Note: These instructions are intended as an example running under Linux. The actual configuration of an NFS mounted share may differ and is dependent on the systems used on your network. Configuration files in the /home/vcf/srv/vcf/config directory and the /home/vcf/srv/maestro directory are backed up to an NFS location under the /home/vcf/var/vcf/data/snapshots directory.


NFS Server Configuration


On the intended NFS server and at a Linux prompt perform the following steps:


1)Run sudo apt-get update

2)Run sudo apt install nfs-kernel-server

3)Create the share directory. For example: /var/remote_unum_backups

4)Add this directory to the /etc/exports file. using an editor such as nano and add the following line:

/var/remote_unum_backups *(rw,sync,no_subtree_check).

5)Run chmod 777 on the /var/remote_unum_backups folder.

6)Restart NFS services using  sudo service nfs-kernel-server restart.

7)Run the command showmount -e to display the export list. In this example, the output is:

Export list for <my_nfs_server_name>:

/home/vcf/remote_unum_backups *
