Dell EMC Avamar for Windows Servers 19.7 User Guide

How Avamar works in a Windows Server cluster

Avamar uses a federated architecture to back up and restore file system data on shared storage in Windows failover cluster or server cluster environments. This is supported on all supported Windows Server platforms.

Avamar supports both active/passive and active/active cluster configurations with two or more nodes.

The following figure illustrates a Windows Server cluster environment with Avamar.

You install the Avamar Client for Windows on each node in the cluster. Then you run the Avamar Cluster Configuration Tool to configure the Avamar federated cluster client. The Avamar federated cluster client serves as a client for the virtual server that provides access to the file system data on the shared failover cluster disk.

When you perform a backup, you select the Avamar federated cluster client as the client to back up. The federated cluster client ensures that Avamar can access the data regardless of which node is managing the data.

You use the Avamar Plug-in for the Windows File System to perform the backup. The Windows File System plug-in is installed when you install the Avamar Client for Windows.
