System Requirements for Linux

Verify that your environment meets the system requirements for the Linux file system.

Operating System

Important

Use the most recent version of the operating system that is listed. The Commvault software fully supports the most recent version of an operating system, until the vendor ends support. More recent versions of the Commvault software might not install on operating systems that are not supported by the vendor anymore. For information about the support lifecycle of an operating system, contact the vendor.

Linux

Important

If you have SELinux enabled on the client computer, create the SELinux policy module as a root user before performing a backup. The SELinux Development package must be installed on the client.

Note

It is recommended that the volume where the software and Job Results will be installed (by default /opt), the volume where logs are stored (/var), and the /tmp folder all be partitioned as separate volumes from the root (/) folder.

Clustering

If clustering is supported by the operating system, you can install the software on a cluster. For information about supported cluster types, see Support for Cluster Configuration.

Memory (RAM)

2 GB or more
An additional 1.5 GB for every 500,000 folders in the backup data

Port Requirements

For information on the ports required for backups to be successful, see Port Requirements for Commvault.

Net-Tools Package

On Red Hat Enterprise Linux/CentOS 7.1 computers, make sure to install the net-tools package.

PowerPC Processor

Commvault supports both of the 64-bit PowerPC architectures: ppc64 (or "big endian") and ppc64le (or "little endian").

Note

For operating systems versions that support the PowerPC architecture, refer to the supported operating systems table above.
Red Hat Enterprise Linux/CentOS 6.x with glibc 2.12.x on PowerPC architecture is not supported effective version 11. For more information about deprecated platforms, see End-of-Life, Deprecated and Extended Support - Platforms.

Schedule Jobs Using a Client Computer's Time Zone

The client computer has to be in one of the standard time zones recognized by the CommServe server. Otherwise, the CommServe server is not updated with the client computer's time zone and the jobs scheduled using the client computer's time zone might not run.

Miscellaneous

Use Commvault Driver Modules on a Linux Computer with UEFI Secure Boot Option Enabled

If the UEFI Secure Boot option is enabled on the Linux computer, Commvault keys must be enrolled in the MOK (Machine Owner Key) list stored in the UEFI NVRAM so that the kernel recognizes the signature of the Commvault driver modules. See Use Commvault Driver Modules on a Linux Computer with UEFI Secure Boot Option Enabled.

Supported Disks

Azure Ultra Disk Storage is supported.

Supported Linux File Systems

Azure Netapp Files (ANF) Service
B-tree File System (Btrfs)

For NSS volumes to preserve the trustee information and permissions, you must enable the Linux extended attributes (XAttr) option prior to running a backup job. For more information on enabling the XAttr option, see the Novell documentation site. At the time of restore, you must select the Restore ACLs option to restore the trustee information and permissions along with the data.

What Is Backed Up

Regular files and directories, including the following, are backed up:

Files that have holes
Raw device files
Files that have advisory locks
A maximum path level of 10 symbolic links pointing to each raw device
Files that have names that contain non-ASCII characters, if the appropriate locales are set
Shares that have Macintosh file system data
Symbolic links that are browsed or manually added to the data contents
Files that have a file path or a file name that contains more than 1023 characters

Note

By default, files that have a mandatory lock are not backed up. To back up these files, see Configuring Backups for Locked Files.

DISCLAIMER

Certain third-party software and service releases (together, "Releases") may not be supported by Commvault. You are solely responsible for ensuring Commvault’s products and services are compatible with any such Releases.
