Configuring Backup Proxy

In the backup infrastructure, a backup proxy is a 'data mover' component responsible retrieving and transferring VM data. During backup or replication activities, the backup proxy retrieves VM data from the source datastore, processes it and transfers to the destination storage. The backup proxy is also used to write data back to the source datastore during full VM restore and VM disk restore.

The role of a backup proxy can be assigned to a Microsoft Windows machine (physical or virtual) that meets system requirements.

To retrieve VM data from the source datastore and write it back to the datastore during restore, the backup proxy can use one of the following modes:

  • Direct storage access — in this mode, the backup proxy copies VM data directly from shared storage, without impacting source hosts.
  • Virtual appliance — in this mode, the backup proxy retrieves VM data directly from storage through hypervisor I/O stack by hot-adding to a proxy VM virtual disks of a processed VM.
  • Network — in this mode, the backup proxy retrieves VM data through hypervisor network stack using NBD protocol over host management interface.

You can explicitly select the transport mode that a backup proxy will use or let Veeam Backup & Replication automatically choose the most appropriate mode.

The backup proxy must provide an optimal route for VM data traffic. When configuring a backup proxy, you need to analyze the connection between the source datastore and a backup proxy. Consider the following recommendations:

  • If you use FC SAN, assign the role of a backup proxy to a physical server with direct FC access to the SAN to enable LAN-free data retrieval.
  • Otherwise, assign the role of a backup proxy to a VM on an ESX(i) host connected to the source storage. This type of a backup proxy enables LAN-free data retrieval during backup and replication and LAN-free writing of data back to the storage during full VM restore. Moreover, it does not require you to provision a dedicated physical server.

Evaluation Case

In this exercise, you will configure a 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 a backup proxy.
  2. Assign the role of a backup proxy to the added server.

Prerequisites

Procedure

To configure a 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 Backup Proxy

  1. At the Credentials step of the wizard, specify credentials for the user account with Administrator 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 Backup Proxy

  1. Follow 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 VMware Backup Proxy to launch the New VMware Proxy wizard.

Assign 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 Backup Proxy

  1. In the Transport mode field, leave the Automatic selection option selected. Veeam Backup & Replication will analyze the backup proxy configuration, define to which datastores it has access and automatically select the best transport mode depending on the type of connection between the backup proxy and the source datastore.
  2. In the Connected datastores field, leave the Automatic detection option selected. If you use SAN storage, Veeam Backup & Replication will automatically detect all datastores that the backup proxy can access in the Direct storage access mode.
  3. Follow next steps of the wizard. At the last step of the wizard, click Finish to finalize configuration of the 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 backup proxy is available in the working area.
