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 & 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 (included in the setup)
  • Microsoft SQL Server System CLR Types (both for 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++ 2015-2019 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.
