System Requirements

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

Veeam Backup Enterprise Manager

Server Side

Enterprise Manager on Linux (Veeam Software Appliance)

Specification	Requirement
Hardware	CPU: x86-64 processor (minimum 8 cores recommended). Memory: 16 GB RAM plus 500 MB RAM for each concurrent job. Disk 1: 240 GB minimum. This disk hosts Veeam JeOS, Veeam Backup & Replication software, configuration database and instant recovery cache. Recommended sizing depends on the number of protected workloads: 480 GB SSD for small environments (up to a few hundred workloads) 960 GB SSD for medium-sized environments (up to a few thousand workloads) Multi-TB SSD for large environments. Larger capacity increases the disk space available to instant recovery cache, allowing for running more machines for longer time. Disk 2: 240 GB minimum. This disk hosts guest file system catalogs and backups, therefore recommended sizing depends on your backup storage needs. Any additional disks found in the system will be automatically joined with Disk 2 into the single Logical Volume Manager (LVM) spanned volume. Note: Software RAID (madm) is not supported. RAID controller with battery or capacitor backed write cache is highly recommended for performance and reliability reasons. Network: 1 Gbps or faster for on-site backup and replication, and 1 Mbps or faster for off-site backup and replication. High latency and reasonably unstable WAN links are supported. Server Hardware: Veeam offers “Veeam Ready - Appliance” certification for hardware vendors. This certification ensures verified and certified compatibility, delivering an optimal customer experience through additional requirements for direct technical collaboration between vendors. Veeam also acknowledges that some customers may need to use existing hardware. As current compatibility guidance, we expect that most systems listed on the RHEL Hardware Compatibility List (HCL) will be compatible with Veeam Software Appliance.
Software	VMware vSphere ESXi 7.0 U2 (7.0.2) or later for OVA deployments. Veeam Software Appliance ISO deployment to a virtual machine is supported, provided the hypervisor is listed as supported by Veeam.

Enterprise Manager on Windows

Specification	Requirement
Hardware	CPU: x86-64 processor. Memory: 8 GB RAM (minimum recommended). 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 11 (from version 22H2 to version 25H2) Microsoft Windows 10 22H2 Microsoft Windows 10 LTSC 2021
PostgreSQL	Local or remote installation of PostgreSQL 14.x, 15.x or 17.x (version 17.6 is included in the 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 2025 Microsoft SQL Server 2022 Microsoft SQL Server 2019 Microsoft SQL Server 2017 Microsoft SQL Server 2016 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 4.8 (included in the setup) .NET Hosting 8.0.21 (included in the setup) Microsoft Visual C++ Redistributable 14.40.33810.0 (included in the setup) Microsoft SQL Server System CLR Types 2014 (both for SQL Server and PostgreSQL, included in the setup) Application Request Routing 3.0.05311 (included in the setup) ASP.NET Core Module 8.0.21 (included in the setup) Microsoft Windows Installer 4.5 Microsoft Internet Information Services 7.5 or later Microsoft URL Rewrite 2.0 for IIS 7
