Limitations and Recommendations
Coexistence with Mission-Critical Production Servers
We do not recommend to 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.
NAS Backup
We recommend to allocate 4 GB RAM for each of the following NAS backup components: backup repository, file proxy, cache repository. For all-in-one installations, make sure you allocate enough memory resources for all components at the same 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, and so on. Additionally, for users with tape installations (for file to tape jobs processing more than 1,000,000 files):
Disk Space: 5 GB1 for product installation and 4.5 GB for Microsoft .NET Framework 4.7.2 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. 1 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 supported1:
1 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. 2 Veeam Backup & Replication supports this version starting from version 10 (build 10.0.1.4854) with cumulative patch 20201202 installed. To learn more details about this patch, see this Veeam KB article. |
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:
If you plan to install Veeam Backup & Replication in the unattended mode using the command line interface, manually install all prerequisite software before that. For more information, see Installing Veeam Backup & Replication in Unattended Mode. |
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. 1 For machines running Microsoft Windows Server 2012 or later. |
For more information, see Backup Server.

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. |
The following storage types can be used as a cache repository for NAS backup:
- Direct attached storage. You can add virtual and physical servers as cache repositories:
- Microsoft Windows server (only 64-bit versions are supported).
- Linux server (only 64-bit versions are supported).
- Network attached storage. You can add SMB (CIFS) Share or NFS Share as a cache repository.
For system requirements of backup repository servers that can be used as a cache repository, see Backup Repository Server.
For more information on the cache repository, see Cache Repository in NAS Backup Support.
Specification | Requirement |
|---|---|

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 versions of the following operating systems are supported:
1 Veeam Backup & Replication supports this version starting from version 10 (build 10.0.1.4854) with cumulative patch 20201202 installed. To learn more details about this patch, see this Veeam KB article. |
For more information, see WAN Accelerators.
|
Global cache is not leveraged by source WAN accelerators, or by WAN accelerators operating in the High bandwidth mode, so it does not need to be allocated and populated in such cases. |
Backups can be performed to the following disk-based storage:
- Local (internal) storage of the backup repository server.
- Direct Attached Storage (DAS) connected to the backup repository server, including external USB/eSATA drives, USB pass through and raw device mapping (RDM) volumes.
- Storage Area Network (SAN). Backup repository server must be connected into the SAN fabric through hardware or virtual HBA, or software iSCSI initiator.
- Network Attached Storage (NAS) able to present its capacity as NFS share (protocol version 3.0 and 4.1 only) or SMB/CIFS share (any protocol version). Using SMB protocol for non-continuously available (CA) file shares is not recommended for reliability reasons. NFS shares are supported both for direct operation and when mounted to a Linux repository server.
