Working with client clusters

About client cluster support

NetVault Backup offers cluster-aware versions of various plug-ins that enable data protection for distributed data. These plug-ins require Cluster Support License Keys.

The cluster nodes are grouped into a Virtual Client on which the cluster-aware plug-in is installed. The backups and restores of cluster nodes are performed through the virtual client.

The following table lists the NetVault Backup plug-ins that can be used in a cluster setup.

Quest NetVault Backup Plug-in for FileSystem

This plug-in is shipped with the NetVault Backup software and can be used to back up the shared file system data on the following platforms:

For more information about the supported cluster software versions, see the Quest NetVault Backup Compatibility Guide. You can download this guide from https://support.quest.com/technical-documents.

A default installation of NetVault Backup does not require licensing of its native Plug-in for FileSystem. However, to use this plug-in a cluster setup, a File System Cluster Support license key is required.

Quest NetVault Backup Plug-in for Exchange

This plug-in can be deployed in an Exchange Server Single Copy Cluster (SCC)/Failover Cluster or Cluster Continuous Replication (CCR) setup to back up the distributed Exchange Server data. For more information, see the Quest NetVault Backup Plug-in for Exchange User’s Guide.

Quest NetVault Backup Plug-in for Hyper-V

This plug-in can be deployed in a Hyper-V failover cluster setup to back up cluster data through a virtual client. For more information, see the Quest NetVault Backup Plug-in for Hyper-V User’s Guide.

Quest NetVault Backup Plug-in for Oracle

This plug-in can be used in Oracle's Real Application Clusters (RAC) setup to back up the distributed Oracle database. For more information, see the Quest NetVault Backup Plug-in for Oracle User’s Guide.

Quest NetVault Backup Plug-in for SQL Server

This plug-in can be used in a SQL Server Failover Cluster setup to back up the distributed SQL Server database. For more information, see the Quest NetVault Backup Plug-in for SQL Server User’s Guide.

Quest NetVault Backup Plug-in for MySQL

This plug-in can be used in a MySQL Server Failover Cluster setup on Linux platform to back up the distributed MySQL Server database. For more information, see the Quest NetVault Backup Plug-in for MySQL User’s Guide.

A virtual client is created when you install a cluster-aware plug-in. All nodes in a cluster are grouped to form a virtual client.

A virtual client is managed like any other NetVault Backup Client. It can be browsed and added to client groups and policies, granted user access, and included in reports. The NetVault Backup Server administers the creation and configuration of a virtual client. The cluster-aware version of the plug-in runs locally on the cluster nodes and the data is processed locally. A cluster node configured as a SmartClient sends data directly to the locally attached storage device.

Device configuration in cluster environment

In a cluster setup, a backup device can be connected in different ways. This section describes the pros and cons of some of the device configuration methods.

Connecting a device to the NetVault Backup Server or Client: This type of configuration allows the control of a robotic arm. However, during backups and restores, the data is transferred over the network.
Sharing drives: A derivative of the previous method can be used by connecting the physical library to the NetVault Backup Server, thus, giving it the control of the robotic arm, and sharing the drive with the cluster nodes. This configuration allows the control of the robotic arm and at the same time enables local data transfers.
Connecting a device to a cluster node: This configuration offers the fastest method of data transfer as the data is routed directly to a locally attached device.
