Access Commvault Storage Using NFS Protocol


Hybrid File Store provides NFS interface to the Commvault Content Store so that users can protect and recover their data by using native NFS client software.

Hybrid File Store does not require any dedicated Commvault Data Agent package on clients, because after the share is mounted, it becomes part of the file system namespace and is accessible to applications through the native file system interface. Applications can seamlessly access their data directly from the backup media.

Hybrid File Store can support powerful use cases, for example running SQL queries on database backups without actually recovering the entire database.

Key Features

  • Provides NFS interface for the Commvault ContentStore.

  • No need to install the Commvault data agent packages on the clients.

  • Supports multiple versions of files.

Solution Overview

The following components comprise a Hybrid File Store system:

  • A CommServe server.

  • A Linux MediaAgent with the Hybrid File Store software. This Linux MediaAgent is the main file server that clients connect to access the store. A dedicated local disk is required for caching the metadata and data.

  • A Linux or Windows MediaAgent computer that acts as an Index Server. To configure the Index Server Cloud, install the Web Server or Index Gateway, the High Availability Computing package, and the Index Store package. You can also use the Linux MediaAgent with the Hybrid File Store software installed as the Index Server.

  • A backup MediaAgent. You can install the MediaAgent on the same machine as Hybrid File Store, or a different machine.

  • NFS clients. NFS clients are any machines that can mount an NFSv3 or NFSv4 share.

    Note: A minimal server install requires one Windows machine for the CommServe, one Linux machine for the Hybrid File Store software, and a Index Store Server.

The table describes the requirements for each component.





Index Store Server (packaged with the Web Server or Index Gateway).

Windows or Linux

Web Server is not supported on Linux platforms, so the Index Gateway package must be installed along with the Index Store package.

Hybrid File Store (packaged with the MediaAgent on Linux)

NFS Clients

Any Operating System with NFS support.

NFS Protocol Support

You can choose the option to use versioning when you create an Hybrid File Store client.

When you enable versioning, the software creates a new version every time the content changes.

Clients must use the NFSV4 protocol for a share that has versioning. NFSV3 clients cannot use a versioning share.

Configuration Interfaces

You can add and manage Hybrid File Store shares through the CommCell Console, Command Center, or using the ConfigureObjectStore command.
