Specifying Preferred Networks for Veeam Plug-ins

You can specify networks over which Veeam Plug-in must transport data when you perform data protection and disaster recovery tasks on remote backup repositories. This setting applies only to Veeam Plug-in network traffic, without affecting the data traffic of other Veeam Backup & Replication components. Setting a dedicated network for Veeam Plug-in backup and replication operations can help to reduce heavy network loads.

Note

Consider the following:

  • By default, if there are no specified preferred networks for Veeam Plug-in data traffic, Veeam Plug-in will connect to preferred networks specified in Veeam Backup & Replication. To learn more about setting preferred networks in Veeam Backup & Replication, see the Specifying Preferred Networks section in the Veeam Backup & Replication User Guide.
  • Veeam Plug-in does not save information about failed network connections. If backup or restore operations fail, Veeam Plug-in tries to connect to the following network from the preferred networks list to finish the started operations. Regardless of the first unsuccessful connection, Veeam Plug-in will try to perform the next backup operations first on the failed network.
  • Veeam Plug-in network preferences take priority over Veeam Backup & Replication network preferences. Only if the preferred networks for Veeam Plug-in data traffic are not available for any reason, Veeam Plug-in will try to connect to the Veeam Backup & Replication preferred networks.

To specify networks for data transfer, you must create a list of preferred networks. When Veeam Plug-in needs to transfer data, it uses networks from this list. If a connection over any of the preferred networks cannot be established for any reason, Veeam Plug-in will automatically fail over to the following network from the preferred networks list.

To create and manage the list of preferred networks that Veeam Plug-in will use, you can perform the following operations:

Adding Preferred Networks

  1. Access the Veeam Plug-in for IBM Db2 directory /opt/veeam/VeeamPluginforDB2 on the server where Veeam Plug-in is installed.
  2. Run the DB2ConfigTool command with the following parameter:

DB2ConfigTool --add-preferred-network <network_IP_address> <position_in_list>

where:

For example:

DB2ConfigTool --add-preferred-network 172.24.29.189 2

Accessing Preferred Networks

  1. Access the Veeam Plug-in for IBM Db2 directory /opt/veeam/VeeamPluginforDB2 on the server where Veeam Plug-in is installed.
  2. Run DB2ConfigTool with the following parameter:

DB2ConfigTool --show-preferred-networks

The following example shows what the output of the DB2ConfigTool command with the --show-preferred-networks parameter can look like:

DB2ConfigTool --show-preferred-networks

Preferred networks:

1. 172.24.29.156

2. 172.24.26.189

Removing Preferred Networks

  1. Access the Veeam Plug-in for IBM Db2 directory /opt/veeam/VeeamPluginforDB2 on the server where Veeam Plug-in is installed.
  2. Run DB2ConfigTool with the following parameter:

DB2ConfigTool --remove-preferred-network <network_IP_address>

where <network_IP_address> can be either the IP address of a single network or a network mask that contains a range of network IP addresses. Specify one of the available options to remove from the preferred networks list.

For example:

DB2ConfigTool --remove-preferred-network 172.24.29.189
