Veeam Backup & Replication provides support for the following versions of the Microsoft Hyper-V platform.
Microsoft Nano Server with Hyper-V role installed is not supported.
Depending on your Windows Server version, some additional hot fixes not included in the Windows Update must be installed. For more information, see this Veeam KB article.
Management Server (optional)
Hyper-V integration components (required for application-aware processing).
1 You can back up VMs of Hyper-V clusters in rolling upgrade. However, Veeam Backup & Replication does not use the Resilient Changed Tracking mechanism in such scenario. To perform backup with RCT enabled, make sure your Microsoft Hyper-V environment meets these requirements. It is recommended to complete the rolling upgrade within four weeks. For more information, see Microsoft Docs.
2 [For Hyper-V 2012 R2 and earlier] Backup and replication of VMs whose data resides on a Hyper-V host volume of 64 TB and larger is not supported.
Supported File Systems
DRBD (Distributed Replicated Block Devices) are not supported.
HFS, HFS+ (volumes up to 2 TB)
The FLR appliance uses module ZFSonLinux version 0.7.0. For this reason, Veeam Backup & Replication supports only those versions of pools and features that are available in ZFSonLinux version 0.7.0.
Consider the following:
- You cannot restore pipes and other file system objects. File-level restore supports recovery of files and folders only.
- [For Microsoft Windows workloads] You can restore files from basic disks and dynamic disks (including simple, mirrored and striped volumes).
- [For Linux workloads] You can restore files from basic disks, Linux LVM (Logical Volume Manager) and ZFS pools. Encrypted LVM volumes are not supported.
- Backup of shared VHDX disks is limited:
- Veeam Backup & Replication backs up shared VHDX disks in a crash-consistent state if they are registered on Microsoft Hyper-V Server 2012 R2.
- Veeam Backup & Replication does not support processing of VMs with shared VHDX disks that are registered on Microsoft Hyper-V 2016 or later. You must change the disk format to VHD Set (VHDS).
Veeam Backup & Replication supports backup of file shares from the following sources:
- Microsoft Windows- or Linux-managed server
- NFS file shares
- SMB file shares
Consider the following requirements and limitations:
- Only 64-bit versions of operating systems are supported for Microsoft Windows- or Linux-managed server file share.
- NFS file share must run NFS protocol version 3 or 4.1.
- Anonymous or AD/Kerberos authentication is not supported for access to file shares through NFS.
In NFS settings of the source file share, you must explicitly specify what servers will have access to the file share.
- SMB file share must run on SMB version 1.x, 2.x or 3.x.
- To support the VSS for SMB File Shares feature, make sure that requirements listed in this Veeam KB article are met.
- To correctly back up SACL (Ownership) files and folders from the SMB file share and restore them:
- When you are specifying access settings for the SMB file share, select the This share requires access credentials check box.
- Make sure that the account you use to access the file share is either added to the Backup Operators group or has the SeBackupPrivilege and SeRestorePrivilege privileges in Windows Server on the file share.

Domain names of all managed servers added to the Veeam backup infrastructure and machines you want to back up must be resolvable into IPv4 addresses.
