Virtual Machine Protection for Microsoft Hyper-V

The Virtual Server Agent provides a unified protection and recovery vehicle for all virtual machine data in a Hyper-V cluster or a standalone Hyper-V server. In addition to protecting entire virtual machines for disaster recovery, the Virtual Server Agent (VSA) also provides granular backup and recovery options. Additional options such as customized automatic discovery, deduplication, and reporting, ensure all your virtual machine data is easily traceable and retrievable whenever the need arises.

The VSA for Microsoft Hyper-V enables you to perform backup and restores and manage virtual machine data in complex virtualized environments.

Key Features

The Virtual Server Agent offers the following key features:

Single Point of Administration

The agent uses a virtualization client that serves as a single point of administration for all cluster nodes. All administrative activities, such backups, restores, schedules, reports etc., can be performed from the virtualization client.

To perform backup operations, each virtualization client can include multiple proxies where the Virtual Server Agent is installed.  The virtualization client also enables proxy teaming, enabling proxy failovers for fault tolerant backups. Using multiple proxies for each virtualization client makes it possible to perform backups for a large number of virtual machines in a limited backup window.

Automatic Protection for All Virtual Machines in a Cluster or Server

After you configure the Virtual Server Agent for a cluster or a server, all virtual machines in the Hyper-V cluster or server are automatically selected for backup. This behavior is designed to ensure that all virtual machines are backed up.

Protection of Migrated Virtual Machines

The cluster is seamlessly backed up even if the virtual machine migrates from one host to another. When the cluster is backed up, the incremental backup cycles are also maintained.

Customized Discovery

If you want to backup only specific virtual machines in a cluster or a server, you can set criteria to search the virtual machines and automatically select them for backup. This is useful in environments where virtual machines are frequently added or removed . You can easily browse and select objects such as CSV or hosts, to set criteria for automatic discovery.

Customized Filters

If you want to exclude specific virtual machines from the backup, you can set criteria to filter virtual machines.

Report

You can view a detailed report about each backed up virtual machine. It contains information such as size of the data, status of integration services, guest operating system, the host on which the virtual machine is running, and so on. You can view all this information from the CommCell console when the backup job is running. It appears on the Virtual Machine Status tab of the View Job Details dialog box.

Block Level Deduplication

Deduplication provides an effective way of storing data by identifying and then eliminating the duplicate items in a data protection operation.

Deduplication at the data block level compares blocks of data against each other. If virtual machines contain blocks of data that are identical to each other, block-level deduplication eliminates the storage of redundant data and reduces the size of the data in storage. This elimination dramatically reduces the virtual machine backup data copies on both the disk and tapes.
