32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- CommServe
- Central Commvault server holding the SQL Server database, configuration, job metadata, and security policy. It coordinates jobs but does not move backup data itself.
- MediaAgent
- Server that moves data between clients and storage libraries. One MediaAgent can serve many clients and can front disk, tape, or cloud libraries at once.
- Subclient
- Smallest protectable unit in Commvault. It defines content paths, storage policy association, schedule, and backup options, and every agent has a default subclient.
- Index Cache
- Metadata store on the MediaAgent used for browse and restore operations. If lost, a catalog rescan from media is required, but the backup data itself is not lost.
- Storage Policy
- Container that maps subclient data to one or more copies. Each copy targets a library through a MediaAgent, and retention is applied per copy.
- Auxiliary Copy
- Job that copies data from one storage policy copy to another. It can run on schedule or on demand and can be throttled to limit network and MediaAgent load.
- Deduplication Database
- DDB holding block signatures and references for deduplicated data. It can be partitioned across MediaAgents and must be sized for expected growth.
- Synthetic Full
- Backup that combines a previous full with later incrementals into a new full without reading the client. It shortens backup windows and reduces client load.
- Copy Precedence
- Order in which storage policy copies are selected for restore. Marking a copy read-only or offline shifts restore traffic to another copy.
- Incremental vs Differential
- Incremental backs up changes since the last backup of any type; differential backs up changes since the last full. Restore chains differ accordingly.
- SQL Log Backup
- Transaction log backup for SQL Server requiring the Full or Bulk-Logged recovery model. It enables point-in-time restore and truncates the log.
- Oracle RMAN Integration
- Commvault Oracle agent uses RMAN to run full, incremental, and archive log backups. Restore supports point-in-time recovery to a specified SCN or time.
- VSS Quiescing
- Windows Volume Shadow Copy Service freezes application writes to produce a consistent snapshot. Used for application-aware backups of files, SQL, and Exchange.
- Out-of-Place Restore
- Restore to an alternate client or path rather than the original location. The destination client must be registered and accessible to the CommServe.
- Virtual Server Agent
- Agent protecting VMware, Hyper-V, and Nutanix workloads. It reads VM disk data through a proxy MediaAgent and supports full and incremental VM backups.
- Changed Block Tracking
- VMware feature that tracks changed disk blocks for incremental backups. It must be enabled on the VM and reset if the change ID becomes invalid.
- Hot-Add Transport
- VMware transport mode that mounts the VM disk to the proxy for reading. It avoids network overhead but requires the proxy on the same host or datastore.
- IntelliSnap
- Array-based snapshot integration for near-instant copies. The snapshot engine is configured per array and referenced by the subclient for snapshot backups.
- Live Recovery
- Feature that mounts a VM backup and boots or browses it without a full restore. It uses a temporary datastore or NFS export on the proxy.
- Role-Based Access
- Commvault security model using users, groups, roles, and security associations. Roles define permissions; associations bind them to entities such as clients.
- Tenant Isolation
- Multi-tenant separation of clients, users, and storage by company. A tenant administrator cannot view or restore another tenant's data.
- Retention Lock
- WORM-style protection preventing deletion of backup data before the lock period expires. It supports compliance requirements and cannot be overridden by administrators.
- Audit Trail
- Log of administrative actions and job events stored in the CommServe database. It can be exported for compliance review and forensic analysis.
- Job Waiting State
- Job state indicating a resource conflict such as a busy drive, busy MediaAgent, or unavailable library. Resolving the resource allows the job to run.
- DR Backup
- Scheduled backup of the CommServe database and configuration to a configured DR location. It is the basis for rebuilding the CommServe after disaster.
- Upgrade Order
- CommServe first, then MediaAgents, then clients. The CommServe version must be equal to or higher than the version of its MediaAgents.
- DDB Verification
- Maintenance process that checks deduplication database consistency. It can detect and repair signature errors and should be scheduled during low activity.
- REST API Authentication
- Login call returns a token used in the Authtoken header for later requests. The API is served over HTTPS under the Command Center or web console path.
- qoperation CLI
- Command-line tool on the CommServe for scripted job control and status queries. It supports starting, stopping, and querying jobs without the console.
- Workflow Automation
- Chained tasks with conditional logic, such as backup followed by auxiliary copy and notification. Workflows react to schedules or events.
- SLA Report
- Report comparing completed backups against defined objectives. Missed objectives appear in the report and can trigger alerts for follow-up.
- Service Account Automation
- Dedicated account with least-privilege role used for scripts and integrations. It limits the impact of compromised credentials compared with administrator accounts.
