Getting Started - OSSV Plug-In - Overview

Table of Contents


The OSSV Plug-In agent provides a simplified end-to-end backup and recovery solution for the data residing on a client computer. The OSSV Plug-In creates a relationship between the client and a secondary file server using the NetApp Open Systems SnapVault (OSSV) Agent and VSS/QSnap. This relationship allows the creation of an OSSV volume, which contains the data from the client, on the secondary file server. The MediaAgent takes the role of a Data Management Agent to allow the NetApp OSSV agent to transfer the data from the client to the file server.

In addition to complete protection of file system and application data, the OSSV Plug-In also provides more granular backup and recovery options that operate seamlessly with your data protection.

Key Features

The OSSV Plug-In offers the following key features:

Comprehensive Backup and Restore Capabilities

The OSSV Plug-In provides the flexibility to backup and restore the data residing on various client computers. You can perform one full backup of the entire data or many incremental backups. The backup data can be restored to different client computers.

The OSSV Plug-In also provides the capability to make a copy of the OSSV volume backup and send it to media. These copies use the NAS backup and restore process.

Heterogeneous Environment Support

You can backup the data on LUNs from file servers other than NetApp (e.g., HDS or EMC). The OSSV Plug-In reads these LUNs on your client as local volumes, allowing you to perform regular backup and restore operations.

Efficient Job Management and Reporting

You can view and verify the status of the backup and recovery operations from the Job Controller and Event Viewer windows within the CommCell Console. You can also track the status of the jobs using reports, which can be saved and easily distributed. Reports can be generated for different aspects of data management. You also have the flexibility to customize the reports to display only the required data and save them to any specified location in different formats. For example, you can create a backup job summary report to view at-a-glance the completed backup jobs.

In addition, you can also schedule these reports to be generated and send them on email without user intervention.

Block Level Deduplication

You can perform deduplication on the OSSV volume created on the file server during backup. Deduplication provides a smarter way of storing data by identifying and eliminating the duplicate items in a data protection operation.

Deduplication at the data block level compares blocks of data against each other. If an object (file, database, etc.) contains blocks of data that are identical to each other, then block level deduplication eliminates storing the redundant data and reduces the size of the object in storage. This way dramatically reduces the backup data copies on both the disk and tapes.

Add-on Components

File System Restore Enabler

The File System Restore Enabler allows data that was backed up from a NetApp file server to be restored to a Windows or Unix computer. A file system restore is a cross-platform restore, where the data is restored to a computer with a different operating system e.g., data from a NetApp file server running ONTAP can be restored to a Windows computer.


The OSSV Plug-In documentation uses the following terminology:


The computer in which the Agent is installed and contains the data to be secured.


The volume containing the client computer data used for backup and restore operations.

File Server

A device used for backup or archival purposes.

OSSV Volume

A volume created on the file server which contains the data from the client.

Data Management Agent

An agent that manages the OSSV backup process.

SnapVault Snapshot

A snapshot of the OSSV volume on the file server.
