System Requirements

Veeam Backup & Replication

Veeam Backup & Replication version 12.3 must be deployed on the backup server.

Backup Server

The backup server is the configuration, administration and management core of the backup infrastructure. It must meet system requirements described in the Backup Server System Requirements section in the Veeam Backup & Replication User Guide.

Veeam Backup & Replication Console

The Veeam Backup & Replication console is a client-side component that provides access to the backup server. The consoles installed on Microsoft Windows Server 2012 2012 or 2012R2 do not support Veeam Backup for Microsoft Entra ID. For other system requirements, see the Veeam Backup & Replication Console System Requirements section in the Veeam Backup & Replication User Guide.

By default, the console is installed locally on the backup server. If you plan to use the local console, make sure that you do not install Veeam Backup & Replication on Microsoft Windows Server 2012 2012 or 2012R2. If you plan to use a remote console, you can install Veeam Backup & Replication on any supported OS.

General-Purpose Backup Proxy

The general-purpose backup proxy processes and transfers data. Veeam Backup for Microsoft Entra ID uses the default general-purpose backup proxy that is deployed on the backup server. The system requirements for the backup server are described in the Backup Server System Requirements section in the Veeam Backup & Replication User Guide.

Microsoft Entra ID Backup Repository

The Microsoft Entra ID backup repository stores tenant backups. This repository is based on a PostgreSQL instance. The requirements for this instance are the same as for the PostgreSQL instance that stores configuration database on the backup server. For more information, see the Configuration Database row in Backup Server System Requirements section in the Veeam Backup & Replication User Guide.

Cache Repository

The cache repository stores temporary cache files for log processing. This repository must meet system requirements described in the Cache Repository System Requirements section in the Veeam Backup & Replication User Guide.

Log Backup Repositories

The primary and secondary log backup repositories store audit and sign-in log backups and their copies. These repositories must meet requirements described in the Backup Repository System Requirements section in the Veeam Backup & Replication User Guide.

For information on which types of repositories can be used as primary and secondary repositories, see Configuring Repositories.
