Commvault® software provides agents for all major file system and applications. Agent support includes traditional streaming backups, built-in content-aware deduplication, Commvault OnePass® archiving, block-level protection, and hardware snapshot capabilities. It is important to note that these capabilities are inherent in the code and can be enabled within the agent.
Commvault agents are categorized using the following general principles:
- Granular agents including file and mailbox agents
- Database agents
- Hypervisor agents
...
File System agents
...
Application agents use application consistent point-in-time protection for application databases. Granular application protection for Exchange, SharePoint, and Lotus Notes provides flexible data protection strategies and simplified recovery methods.
...
File system agents provide the fundamental data protection strategy in all data centers. File agents are supported for all major operating systems and

It is important when deploying agents, to validate requirements. Prerequisites differ from one type to another. Even for components that you frequently deploy, always confirm as it may change when a new service pack is released.
Most frequent requirement categories:
- Operating system version
- Application version (for application agents)
- Service account with specific privileges
For more information on requirements, please refer to their respective section on Commvault's online documentation.
The Virtual Server Agent (VSA) provides complete virtual machine (VM) protection and granular recovery of virtual machine data without the need to install traditional agents within a VM. Based on APIs provided by the hypervisor, different protection and recovery capabilities are possible.
...
Archiving removes infrequently accessed data from production storage. This reduces backup and recovery windows and provides a greater return on investment by reducing production storage footprints. File system data, Network Attached Storage (NAS) data, Exchange mailbox, virtual machines and some database applications support Commvault OnePass® archiving.
...
IntelliSnap® technology integrates regular protection methods with hardware-based snapshot technologies to coordinate and manage disk snapshots. This integration allows for application-aware snapshots to be conducted for file systems, applications, and virtual environments.

Deploying agents can be achieved in several ways:
Available agent deployment methods:
- Push install
- Interactive install
- Custom package
Agent deployment best practices:
- If DNS names are used, ensure the DNS is properly resolving the name forward and reverse.
- If deploying an agent on a remote site, consider using a remote software cache or transfer a custom package.
- If the client is behind a firewall blocking ports, set network configurations to tunnel communication in a port.
Push Install
From the Tools menu | Click Add/Remove Software | Install Software
The CommCell® console is used to push the Commvault® software to clients. The following specific ports are used to achieve the install:
- Commvault base services – Ports 8400 and 8401 are used
- Linux – port 22 is required
- Windows — ports 135, 139, 445 are required
