Antivirus Exclusions for Windows

To ensure stable, optimal performance for your Commvault access nodes, you must exclude certain folders and files from antivirus read, write, and scan processes.

Improperly configured antivirus exclusions can cause outages of applications and services due to contention or file locking. For example, antivirus software might lock the collect files that are generated during a backup. Also, most virus-scanning applications use real-time scanning, which can degrade performance or cause failures during Commvault backups and other operations.

Test Commvault features and and functions. During normal operations, monitor Commvault processes and how those processes interact with antivirus software. Coordinate with your antivirus software vendor to achieve proper configuration and tuning of the antivirus software. The goal is for the antivirus software's rules and schedules to allow Commvault operations to run normally and complete successfully.

The information provided is not a complete list of exclusions because the Commvault software might change with updates and new releases.

Important

  • Make sure that no scheduled or on-demand antivirus scans run during Commvault backups.

  • Degraded backup performance and unknown backup failures might be caused by host intrusion prevention systems (HIPS).

  • If you experience performance and consistency problems with SQL Server when certain modules are loaded into the server, see Microsoft KB 2033238.
