Specifying Preferred Networks for Data Transfer

You can choose networks over which Veeam Backup & Replication must transport VM data when you perform data protection and disaster recovery tasks. This option can be helpful if you have a non-production network and want to route VM data traffic over this network instead of the production one.

Preferred network rules are applied to the following backup infrastructure components:

• Backup proxies
• Backup repositories
• WAN accelerators
• Gateways (used with backup repositories)
• Log shipping servers
• Tape servers
• Storage systems: EMC VNX and VNXe, HPE 3PAR StoreServ, HPE StoreVirtual P4000 series, HPE StoreVirtual VSA, NetApp

To define networks for data transfer, you must create a list of preferred networks. When Veeam Backup & Replication needs to transfer VM data, it uses networks from this list. If a connection over preferred network(s) cannot be established for some reason, Veeam Backup & Replication will automatically fail over to the production network.

To set a network priority list:

1. From the main menu, select Network Traffic.
2. In the Global Network Traffic Rules window, click Networks.
3. In the Preferred Networks window, select the Prefer the following networks for backup and replication traffic check box.
4. Click Add.
5. Specify a network address using a CIDR notation or a network mask and click Add.
6. Repeat steps 4-5 for all networks that you want to add.
