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.
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):
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. * Here and throughout this document GB is considered as 2^30 bytes, TB as 2^40 bytes. |
OS | Only 64-bit version of the following operating systems are supported*:
* Running Veeam backup server or any of Veeam backup infrastructure components on Insider versions of Microsoft Windows OS (both Client and Server) is not supported. |
Software | During setup, the system configuration check is performed to determine if all prerequisite software is available on the machine where you plan to install Veeam Backup & Replication. If some of the required software components are missing, the setup wizard will offer you to install missing software automatically. This refers to:
The following software must be installed manually:
|
SQL Database | Local or remote installation of the following versions of Microsoft SQL Server:
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. * For machines running Microsoft Windows Server 2012 or later. |

Specification | Requirement |
|---|---|
Hardware | CPU: x86 processor (x86-64 recommended). Memory: 4 GB RAM, plus up to 2 GB RAM (32-bit OS) or up to 4 GB RAM (64-bit OS) for each concurrent job depending on backup chain’s length and backup files sizes.

If you plan to use a Microsoft Windows backup repository with Data Deduplication, make sure that you set up the Microsoft Windows server correctly. For more information, see this Veeam KB article. |
Specification | Requirement |
|---|---|
Hardware | CPU: x86-64 processor. Using multi-core processors improves data processing performance, and is highly recommended on WAN links faster than 10 Mbps. Memory: 8 GB RAM. Using faster memory (DDR3/DDR4) improves data processing performance. Disk Space: Disk space requirements depend on the WAN Accelerator role. For more information, see WAN Accelerator Sizing. 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. |
OS | Only 64-bit version of the following operating systems are supported:
|
For more information, see WAN Accelerators.
|
Global cache is not leveraged by Source WAN Accelerators, and so does not need to be allocated and populated on WAN Accelerators used only as source ones. |
