Veeam Backup & Replication 9.0

Configuring a Backup Proxy

The offhost backup proxy is a backup infrastructure component that you must configure if you want to perform offhost backup. The role of the offhost backup proxy can be assigned to a physical or virtual machine that meets system requirements. On this machine, Veeam Backup & Replication installs a data mover component responsible data processing and transfer.

During offhost backup, Veeam Backup & Replication triggers a snapshot of a volume on which VMs are located. After that, the snapshot is split from the source Hyper-V host and mounted to the offhost backup proxy. This is made possible due to VSS transportable shadow copies. The transportable shadow copy technology allows you to create a snapshot of a data volume on one server and mount it to another server within the same SAN subsystem. The mount operation is performed at the SAN layer, so your network resources are not impacted. The operation takes only a couple of minutes regardless of the snapshot size.

After the snapshot is mounted, the data mover running on the offhost backup proxy accesses the mounted snapshot, retrieves VM data from it, processes it and transfers data to the destination. As a result, VM processing is offloaded to the offhost backup proxy and the load on the source Hyper-V host is reduced.

Evaluation Case

In this exercise, you will configure an offhost backup proxy. Configuration of a backup proxy is performed in two stages:

  1. In the Veeam Backup & Replication console, add a server that will perform the role of an offhost backup proxy.
  2. Assign the role of an offhost backup proxy to the added server.

Prerequisites

Note that the version of the Hyper-V host and offhost backup proxy must be the same.

Procedure

To configure an offhost backup proxy:

  1. Open the Backup Infrastructure view.
  2. In the inventory pane, right-click the Managed servers node and select Add Server.

Add a Server to Act as a Backup Proxy

  1. In the Add Server window, click Microsoft Windows to launch the New Windows Server wizard.

Choose Server Type

  1. At the Name step of the wizard, specify a DNS name or IP address of a Microsoft Windows server.

Configuring a Backup Proxy

  1. At the Credentials step of the wizard, enter credentials for the user account with administrator access permissions to the added server: click Add on the right of the Credentials field and specify the user name and password to connect to the added server. Credentials must be specified in the DOMAIN\USERNAME format for domain accounts or HOST\USER format for local accounts. Click OK.

If you have specified credentials before, you can simply select them from the Credentials list.

Configuring a Backup Proxy

  1. Follow the next steps of the wizard. At the last step of the wizard, click Finish to add the server.

Next, assign the role of a backup proxy to the added server.

  1. Open the Backup Infrastructure view.
  2. In the inventory pane, right-click the Backup Proxies node and select Add Hyper-V Offhost Backup Proxy.

Assign Off-host Backup Proxy Role to the Server

  1. At the Server step of the wizard, in the Choose server list select the Microsoft Windows server that you have added.

Configuring a Backup Proxy

  • In the Connected volumes field, leave the Automatic detection option selected. Veeam Backup & Replication will automatically detect all volumes to which the configured offhost backup proxy has access.
  • Go through the next steps of the wizard without changing default settings. At the last step of the wizard, click Finish to finalize configuration of the offhost backup proxy.
  • Validation

    1. Open the Backup Infrastructure view.
    2. In the inventory pane, click the Backup Proxies node.
    3. Make sure that the added offhost backup proxy is available in the working area.

    Validate the Add Proxy Operation
