Virtual Machine Protection for VMware
The Virtual Server Agent (VSA) for VMware provides a unified protection and recovery vehicle for all virtual machine data in your vCenter. In addition to complete protection of entire virtual machines for disaster recovery, the Virtual Server Agent provides granular backup and recovery options. Options such as customized automatic discovery, deduplication, and reporting ensure all your virtual machine data is easily traceable and retrievable whenever the need arises.
Note: The Virtual Server Agent may also be referred to as the Virtual Server iDataAgent.
The VSA for VMware enables you to perform backup and restores and manage virtual machine data in complex virtualized environments. VSA uses vStorage APIs for Data Protection (VADP) for data protection, with support for all guest operating systems supported by VADP.
|Single Administration Point||The virtualization client serves a single point of administration for a vCenter or ESX server. All administration activities such as backups, restores, schedules, and reports 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 vCenter||Once you configure the Virtual Server Agent for a vCenter, all virtual machines in the vCenter are automatically selected for backup. This behavior is designed to ensure all virtual machines are backed up.||Default Subclient Coverage|
|To back up only specific virtual machines in a vCenter, you can define rules to discover 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 vCenter objects such as hosts, datastores, and resource pools as criteria for automatic discovery.||Adding Subclient Content|
|Customized Filters||You can add filters to exclude specific virtual machines or virtual machine disks from backups. By combining discovery rules and filters, you can precisely target virtual machines for backup.||Defining Filters|
|Detailed Status for Each Virtual Machine Backup||You can view detailed information about each backed up virtual machine on the Virtual Machine Status tab of the View Job Details dialog box. This dialog box is available from the CommCell Console when a backup job is running. It displays information such as the name of the proxy that performed the backup of the virtual machine, the size of the backup data, and the type of backup.||Viewing Virtual Machine Backup Status|
|vCloud Backup and Restore||You can protect the vCloud-specific attributes of a virtual machine and restore a virtual machine back to a vCloud.||Configuring vCloud Backup|
|Point-in-Time Snapshots of Virtual Machines||IntelliSnap backup enables you to create a point-in-time snapshot of a virtual machine by temporarily quiescing the data, taking a snapshot, and resuming live operations. IntelliSnap backups work in conjunction with hardware snapshot engines.||IntelliSnap for VMware|
|Block Level Deduplication||
Deduplication enables more efficient backups by identifying and eliminating duplicate items in data protection operations.
Deduplication at the data block level compares blocks of data against each other. If a virtual machine contains blocks of data that are identical to each other, block level deduplication eliminates storage of redundant data and reduces the size of the data in storage. Deduplication dramatically reduces virtual machine backup data for copies on all media.
Changed Block Tracking (CBT) is a VMware feature that can be used to optimize backups of virtual machines by reading only the allocated and modified portions of a virtual disk. CBT is automatically enabled for virtual machines running on hardware version 7 or later.
