VSA Proxy

Windows machines can process Windows VMs, and Linux machines can process Linux VMs.

Use a Windows MediaAgent to perform a live browse operation for Windows guest VMs. When you use a Windows MediaAgent for a live browse operation, information for FAT, FAT32, NTFS, ReFS and Storage Spaces file systems is available.


The FREL provides UNIX file system support for ext2, ext3, ext4, XFS, JFS, Btrfs, HFS, and HFS Plus. To enable extended file system recovery for UNIX-based virtual machines, deploy a FREL or convert a Linux MediaAgent to a File Recovery Enabler. For more information, see Converting a Linux MediaAgent to a VMware File Recovery Enabler for Linux.

Hardware Requirements

Index Server Hardware Requirements

The index server must have the MediaAgent, Index Gateway, and Index Store packages installed. For index server MediaAgent hardware requirements, see Hardware Recommendations for the Index Server.

When you enable file indexing on a VM group, the system will push the packages to the MediaAgent that is specified in the associated backup plan or storage policy. That MediaAgent then begins acting like an index server.

It is recommended that you deploy a separate MediaAgent, rather than using a shared computer, for the index server. Make sure that you associate this MediaAgent with the storage plan policy.

Note: If the MediaAgent used in the storage plan or storage policy is the same computer as the CommServe, Web Console, Web Server, or Command Center computer, then you must manually install the required packages on the MediaAgent before you enable file indexing.

VSA Proxy Hardware Requirements

For hardware requirements for a VSA proxy installed on either a physical or virtual machine, see Hardware Specifications for Virtual Server Agent.

File Based Recovery Cache Requirements

You must ensure that there is at least 100 GB of free disk space for the file based recovery (FBR) cache directory.

By default, the FBR cache directory is located under the Job Results directory, unless the FBR cache directory location was changed manually or was deployed from an open virtual appliance (OVA) template.

To change the FBR cache directory location, see "Additional Configuration" in Automatic Configuration of a MediaAgent as a Linux File Recovery Enabler (FREL).

Note: Do not set the path for the FBR cache mount point to the root directory or to the Commvault ransomware protection-enabled directory.
