General-Purpose Backup Proxy

General-purpose backup proxies can be deployed using the Veeam JeOS image by selecting the Infrastructure Appliance option. This enables certificate-based authentication, secure industry-standard communication protocols, and automated updates that are centrally controlled using the Veeam Backup & Replication server.

Note

Component hardware requirements must be added to the Veeam JeOS system requirements to ensure that the assigned role has sufficient CPU and RAM resources.

In addition to this option, you can deploy and manage backup proxies on supported operating systems of your choice.

The following table shows the minimum system requirements for a general-purpose backup proxy used for unstructured data backup and Veeam Agent and storage system snapshot integration.

General-Purpose Backup Proxy

Specification

Requirement

Hardware

CPU: x86-64 processor with 2 cores (vCPUs) minimum. 4 cores (vCPUs) are recommended (2 cores are required) for each additional concurrent task. Using multi-core processors enhances data processing performance and enables the processing of more tasks simultaneously.

Memory: [For unstructured data backup] 4 GB RAM plus 4 GB RAM for each concurrent task.

[For Veeam Agent and storage system snapshot integration] 2 GB RAM plus 1 GB RAM for each concurrent task.

Using faster memory improves data processing performance. For all-in-one installations, where the server performs several roles, it must have enough memory resources for all components.

Disk Space: 300 MB.

Network: High latency and reasonably unstable WAN links are supported.

OS

64-bit versions of the following Microsoft Windows operating systems are supported, including Core edition:

  • Microsoft Windows Server 2025
  • Microsoft Windows Server 2022
  • Microsoft Windows Server 2019
  • Microsoft Windows Server 2016
  • Microsoft Windows 11 (versions 22H2 – 25H2)
  • Microsoft Windows 10 (version 22H2)
  • Microsoft Windows 10 LTS (version LTSC 2021)

64-bit versions of the following Linux distributions are supported:

  • Debian 11.0 to 12.11
  • Oracle Linux 7 to 10
  • RHEL 8.6 to 9.6
  • SLES 12 SP5, 15 SP3
  • Ubuntu 20.04 LTS, 22.04 LTS, 24.04 LTS

Note: The VSS snapshot creation for SMB File Shares feature requires that all requirements listed in this Veeam KB article are met.

[For Veeam Agent and storage system snapshot integration] Backup proxies and Veeam agent computers must run Microsoft Windows Server OS versions. Backup proxies cannot run the OS versions that are earlier than the Veeam Agent computer OS version.
