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 VMware 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 cannot install Veeam Backup & Replication and Veeam Backup Enterprise Manager on a machine running Microsoft Windows Server Core. However, 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.
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 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. Memory: 4 GB RAM plus 500 MB RAM for each concurrent job. Additionally, for users with tape installations (for file to tape jobs processing more than 1,000,000 files):
Disk Space: 2 GB for product installation and 4.5 GB for Microsoft .NET Framework 4.5.2 installation. 10 GB per 100 VM for guest file system catalog folder (persistent data). 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:
|
Software | During setup, the setup performs system configuration check 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 (both Full and Express Editions are supported):
|

Veeam Backup & Replication Console
Specification | Requirement |
|---|---|
Hardware | CPU: x86-64 processor. Memory: 2 GB RAM Disk Space: 500 MB for product installation and 4.5 GB for Microsoft .NET Framework 4.5.2 installation. Network: 1 Mbps connection to the backup server. High latency and low bandwidth impact user interface responsiveness. |
OS | Only 64-bit version of the following operating systems are supported:
|
Software |
|
For more information, see Backup & Replication Console.
Specification | Requirement |
|---|---|
Hardware | CPU: modern x86 processor with minimum of 2 cores (vCPUs). It is recommended to add 1 core (vCPU) for each additional concurrent task. Using faster processors improves data processing performance. For more information, see Limitation of Concurrent Tasks. Memory: 2 GB RAM plus 200 MB for each concurrent task. Using faster memory (DDR3/DDR4) improves data processing performance. Disk Space: 300 MB. 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 |
Versions of a Microsoft Hyper-V host and off-host backup proxy must coincide. For example, if you use a Microsoft Windows Server 2012 machine with the Hyper-V role enabled as a Microsoft Hyper-V host, you must deploy the off-host backup proxy on a Microsoft Windows Server 2012 machine with the Hyper-V role enabled. |
Software | VSS hardware provider that supports transportable shadow copies. The VSS hardware provider is typically distributed as a part of client components supplied by the storage vendor. |
For more information, see Off-Host Backup Proxy.
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. For more information, see Limitation of Concurrent Tasks. 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 | Both 32-bit and 64-bit (recommended) versions of the following operating systems are supported:
|
For more information, see Backup Repository.
|
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 https://www.veeam.com/kb1893. |
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. |
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 and raw device mapping (RDM) volumes.
- Storage Area Network (SAN). Backup repository server must be connected into the SAN fabric via hardware or virtual HBA, or software iSCSI initiator.
- Network Attached Storage (NAS) able to represent itself as SMB (CIFS) share (direct operation), or NFS share (must be mounted on a Linux backup repository server).
- Dell EMC DataDomain (DD OS version 5.4, 5.5, 5.6, 5.7 or 6.0) with DDBoost license. Both Ethernet and Fibre Channel (FC) connectivity is supported.
- ExaGrid (firmware version 4.8.0.351.P28 or later).
- HPE StoreOnce (firmware version 3.13.1 or later) with Catalyst license. Both Ethernet and Fibre Channel (FC) connectivity is supported. Instant VM Recovery support requires firmware version 3.15.1 or later.
Specification | Requirement |
Hardware | LTO3 or later tape libraries (including VTL) and standalone drives are supported. Tape device must be directly attached to the backup server, to a tape server via SAS, FC or iSCSI interface. |
Software |
|
Specification | Requirement |
|---|---|
Hardware | CPU: x86 processor (x86-64 recommended). Memory: 2 GB RAM plus 200MB for each concurrent task. Restoring VMs directly from tape requires 400MB of RAM per 1TB of virtual disk size. Additionally (for file to tape jobs processing more than 1,000,000 files):
Disk Space: 300 MB, plus 10 GB for temporary data storage for backup and restore operations. Network: 1 Gbps or faster. |
