System Requirements

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

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 Server.

  • Microsoft SQL Server 2022
  • Microsoft SQL Server 2019
  • Microsoft SQL Server 2017
  • Microsoft SQL Server 2016

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.


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
  • Microsoft Visual C++ 2015-2019 Redistributable
  • Microsoft SQL Server System CLR Types for SQL Server 2014
  • IIS URL Rewrite Module 2
  • Microsoft Universal C Runtime
  • Microsoft Report Viewer Redistributable 2015
  • Microsoft Internet Information Services:
  • Default Document Component
  • Directory Browser Component
  • HTTP Errors Component
  • Static Content Component
  • Windows Authentication Component
  • WebSocket Protocol Component
  • ASP.NET 4.5 Component
  • .NET Extensibility 4.5 Component
  • 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.



To restore Microsoft Exchange items with Veeam Backup Enterprise Manager, Microsoft Exchange servers must be members of the same Microsoft Active Directory forest.
