Veeam Backup & Replication 9.5 Update 4
User Guide for VMware vSphere

System Requirements

Make sure that servers that you plan to use as backup infrastructure components meet the system requirements listed below.

Limitations and Recommendations

Coexistence with Mission-Critical Production Servers

It is not recommended that you install Veeam Backup & Replication and its components on mission-critical machines in the production environment such as vCenter Server, Domain Controller, Microsoft Exchange Server, Small Business Server/ Windows Server Essentials and so on. If possible, install Veeam Backup & Replication and its components on dedicated machines. Backup infrastructure component roles can be co-installed.

Microsoft Windows Server Core

You can assign roles of a backup proxy, backup repository, WAN accelerator, Veeam Cloud Connect infrastructure components and tape infrastructure components to machines running Microsoft Windows Server Core.
Mind that you cannot install Veeam Backup & Replication and Veeam Backup Enterprise Manager on a machine running Microsoft Windows Server Core.

Domain Member

The machine on which you plan to install Veeam Backup & Replication does not necessarily need to be a domain member. However, if you plan to restore Microsoft Exchange items from the Veeam Backup Enterprise Manager UI, you must install Veeam Backup Enterprise Manager on the domain member server from the Microsoft Active Directory forest in which Microsoft Exchange mailboxes are located.

All-in-One Installations

For all-in-one installations, you can subtract 2 GB of memory resources from each but one role. These 2 GB are allotted to the OS itself, assuming each component is installed on the dedicated server.

Backup Server

Specification

Requirement

Hardware

CPU: x86-64 processor (4 cores recommended).

Memory: 4 GB RAM plus 500 MB RAM for each concurrent job. Memory consumption varies according to number of VMs in the job, size of VM metadata, size of production infrastructure, etc.

Additionally, for users with tape installations (for file to tape jobs processing more than 1,000,000 files):

  • 1,5 GB RAM for file to tape backup for each 1,000,000 files
  • 2,6 GB RAM for file restore for each 1,000,000 files
  • 1,3 GB RAM for catalog jobs for each 1,000,000 files

Disk Space: 15 GB* for product installation and 4.5 GB for Microsoft .NET Framework 4.6 installation. 10 GB per 100 VM for guest file system catalog folder (persistent data). Additional free disk space for Instant VM Recovery cache folder (non-persistent data, at least 10 GB recommended).

Network: 1 Gbps or faster for on-site backup and replication, and 1 Mbps or faster for offsite backup and replication. High latency and reasonably unstable WAN links are supported.
