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.

Consider the following:

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:
- Access the Veeam Plug-in for SAP HANA directory /opt/veeam/VeeamPluginforSAPHANA on the server where Veeam Plug-in is installed.
- Run the SapBackintConfigTool command with the following parameter:
SapBackintConfigTool --add-preferred-network <network_IP_address> <position_in_list> |
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 add as preferred networks for Veeam Plug-in data traffic.
- <position_in_list> is the position number of the network in the preferred networks list. The position in the list determines in what order Veeam Plug-in will connect to the specified network. If you do not chose a specific position in the list, newly added networks take the last place in the list automatically.
For example:
SapBackintConfigTool --add-preferred-network 172.24.29.189 2 |
- Access the Veeam Plug-in for SAP HANA directory /opt/veeam/VeeamPluginforSAPHANA on the server where Veeam Plug-in is installed.
- Run SapBackintConfigTool with the following parameter:
SapBackintConfigTool --show-preferred-networks |
The following example shows what the output of the SapBackintConfigTool command with the --show-preferred-networks parameter can look like:
SapBackintConfigTool --show-preferred-networks Preferred networks: 1. 172.24.29.156 2. 172.24.26.189 |
- Access the Veeam Plug-in for SAP HANA directory /opt/veeam/VeeamPluginforSAPHANA on the server where Veeam Plug-in is installed.
- Run OracleRMANConfigTool with the following parameter:
SapBackintConfigTool --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 addresses. Specify one of the available options that you want to remove from the preferred networks list.
For example:
SapBackintConfigTool --remove-preferred-network 172.24.29.189 |
