Veeam ONE Architecture
Veeam ONE relies on client-server architecture to work effectively in environments of any size and complexity. Veeam ONE architecture includes the following structural components:
- Veeam ONE Server
Veeam ONE Server is responsible for collecting data from virtual, Veeam Backup & Replication and Veeam Backup for Microsoft 365 servers, and storing this data in the database. As part of Veeam ONE Server, the following components are installed: Veeam ONE Monitoring Service, Veeam ONE Reporting Service, Veeam ONE Error Reporting Service, and Veeam ONE Web API.
- Veeam ONE Web Services
Veeam ONE Web Services enable access to Veeam ONE web server and handle rendering of reports.
- Veeam ONE Client
Veeam ONE Client is a client component of Veeam ONE Server. Veeam ONE Client communicates with the Veeam ONE Server installed locally or remotely.
- Veeam ONE Monitoring Database
Veeam ONE Monitoring database stores data used by product components. The database is hosted on a Microsoft SQL Server that can run remotely, or can be co-installed with other Veeam ONE components.
- Veeam ONE Reporting Database
Veeam ONE Reporting database stores data used by product components. The database is hosted on a PostgreSQL server that can run remotely, or can be co-installed with other Veeam ONE components. Temporary tables are deleted when the Reporter session ends, or after a timeout if the session-based deletion does not occur.
- Veeam ONE Analytics Service
Veeam ONE Analytics service is a component that enables communication with Veeam Backup & Replication servers, performs collection of logs, and sends remediation commands.
Veeam ONE Analytics service is configured when adding Veeam Backup & Replication servers to Veeam ONE to improve data collection performance in large-scale Veeam Backup & Replication infrastructures. For details on Veeam ONE Analytics service, see Veeam Intelligent Diagnostics.
Veeam ONE Analytics service can work in the following modes:
- Server
In this mode, Veeam ONE Analytics service is responsible for analyzing log data and signature updates.
Veeam ONE Analytics service server is included into Veeam ONE installation package and is automatically deployed on the machine running Veeam ONE server during product installation.
- Client
In this mode, Veeam ONE Analytics service is responsible for collecting logs and executing remediation actions on Veeam Backup & Replication servers.
By default, Veeam ONE Analytics service client is deployed on Veeam Backup & Replication servers when you connect these servers to Veeam ONE.
Veeam ONE architectural components are installed on a single machine, or run on dedicated machines. For details, see Deployment Scenarios.
