Cluster Support

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

Hard Drive

1 GB of minimum disk space is required for installing the software.

To calculate the disk space requirements for the job results directory, see Job Results Directory Disk Space Calculation. Some agents and components require additional disk space, see Agents and Components Requiring Additional Disk Space.

500 MB of free disk space is required for the log directory.

Supported File Systems

All of the blocks in a raw or block device are backed up during block-level backups. For supported file systems, only the blocks that contain data are backed up.

The following table lists the file systems supported for each supported operating system:

File System

Operating System

CVBF

Data Blocks Backup Support

Extended 3 File System (ext3)

Linux

Yes

Yes

Extended 4 File System (ext4)

Linux

Yes

Yes

'X' File System (XFS)

Linux

Yes

Yes

Virtual FAT (vfat)

Linux

Yes

No

Journal File System (JFS2)

AIX

Yes

Yes

UNIX File System (UFS)*

Solaris

Yes

No

Veritas File System (VxFS)

Solaris, AIX

Yes

Yes

Zettabyte File System (ZFS)*

Solaris

Yes

No

Note:

  • Live browse and file-level restores are not supported for raw devices.
  • ZFS must span the entire disk; disk slices are not supported.
  • For Solaris File System Agent, the CVBF cache must be a UFS file system. For example, /opt/commvault/CVBF/cache.

Supported Volume Managers

  • AIX LVM
  • Linux LVM
  • VxVM

Space Requirements in the LVM Group

  • For Linux LVM snaps, there must be adequate free space in the LVM volume group for snapshot creation. The default COW cache size is set to 4096 MB or 5% of the volume size, whichever is greater. To increase the COW cache size, configure the nSnapCowSizeMB additional setting. For instructions on adding the additional setting, see Adding or Modifying Additional Settings from the CommCell Console.
  • For CVBF snaps, the COW files are created in the software_install_path/CVBF/cache directory by default. Over time, the COW files can grow significantly and fill up the volume. To move the COW files to another volume, configure the sCVBFSNAPPART additional setting. For instructions on adding the additional setting, see Adding or Modifying Additional Settings from the CommCell Console.

Supported Devices

  • VirtIO

Location of the Default Temporary Directory for Commvault Software

For Unix clients, the default temporary directory location /opt/commvault/Base/Temp for the Commvault software must be under the same mount point as the Job Results folder. You can set the default temporary directory for the software by configuring the dGALAXYTEMPDIR registry key on the client computer.

For instructions about adding an additional setting from the CommCell Console, see Adding an Additional Setting from the CommCell Console.

DISCLAIMER

Third-party maintenance (minor) releases or feature releases that are supported by the Commvault software may not be listed in our System Requirements. When possible, Commvault provides information on any known issues related to these minor releases or feature releases. In some cases, these minor releases or feature releases affect how the Commvault software works. Commvault software may experience changes in functionality as the result of the third-party minor release or feature releases. These changes are beyond the control of Commvault. Platforms that are supported in the current version of Commvault software may not be supported in earlier versions of the software. Contact your software provider to ensure that third-party minor releases or feature releases are compatible with the Commvault software.

Additional considerations regarding minimum requirements and End-of-Life policies from third-party vendors also apply.
