System Requirements

Make sure that servers that you plan to use as Veeam Backup Enterprise Manager infrastructure components meet the system requirements listed in this section.

All backup servers must be based on the same database engine as Veeam Backup Enterprise Manager (PostgreSQL or Microsoft SQL Server). For more considerations and limitations on adding backup servers, see Adding Backup Servers.

Veeam Backup Enterprise Manager

Hard disk space: 2 GB for product installation plus sufficient disk space to store guest file system catalog from connected backup servers (according to data retention policy). Network: 1 Mbps or faster connection to Veeam Backup & Replication servers. Slow or unstable links will impact the performance of Veeam Backup Enterprise Manager data collection operations from Veeam Backup servers.
OS	64-bit versions of the following operating systems are supported: Microsoft Windows Server 2025 Microsoft Windows Server 2022 Microsoft Windows Server 2019 Microsoft Windows Server 2016 Microsoft Windows Server 2012 R2 Microsoft Windows Server 2012 Microsoft Windows 11 (versions 21H2, 22H2, 23H2) Microsoft Windows 10 (versions 1909 to 22H2) Microsoft Windows 10 LTS (versions LTSB 1607, LTSC 1809, LTSC 2021)
PostgreSQL	Local or remote installation of the following versions of PostgreSQL: PostgreSQL 14.x PostgreSQL 15.x (version 15.10.1 is included in the Veeam Backup & Replication 12.3 setup) Note that Veeam Backup Enterprise Manager does not support PostgreSQL installations on cloud database services (for example, Amazon Relational Database Service (RDS).
Microsoft SQL Server	Local or remote installation of the following versions of Microsoft SQL Server (both Full and Express Editions are supported): Microsoft SQL Server 2022 Microsoft SQL Server 2019 Microsoft SQL Server 2017 Microsoft SQL Server 2016 Microsoft SQL Server 2014 with Microsoft SQL Server 2014 Management Objects and Microsoft System CLR for Microsoft SQL Server 2014 Microsoft SQL Server 2012 Microsoft SQL Server 2012 databases and later with compatibility to Microsoft SQL Server 2005 are not supported. All editions of Microsoft SQL Server are supported. The usage of Microsoft SQL Server Express Edition is limited by the database size up to 10 GB. If you plan to have larger databases, use other editions of Microsoft SQL Server. Veeam Backup & Replication and Veeam Backup Enterprise Manager configuration databases can be deployed in Microsoft SQL AlwaysOn Availability Groups. For more information, see this Veeam KB article.
Software	During installation and upgrade, the setup wizard system performs configuration check to determine if all prerequisite software is available on the machine where you plan to install Enterprise Manager. If some of the required software components are missing, the setup wizard tries to install missing software automatically. This refers to the following software: Microsoft .NET Framework 4.7.2 (included in the setup) Microsoft SQL Server System CLR Types (both for Microsoft SQL Server and PostgreSQL, included in the setup) Microsoft Report Viewer Redistributable 2015 (included in the setup) Microsoft Universal C Runtime (included in the setup) Microsoft Visual C++ 2015-2022 Redistributable (included in the setup) Microsoft Internet Information Services 7.5 or later Microsoft URL Rewrite 2.0 for IIS 7 Windows Installer 4.5 (included in the setup) If you plan to install Veeam Backup Enterprise Manager in the unattended mode using the command line interface, manually install all prerequisite software before that. For more information, see the Veeam Backup Enterprise Manager Server subsection of the Installing Veeam Backup & Replication in Unattended Mode section of the Veeam Backup & Replication User Guide.
