Veeam Backup & Replication is a proprietary backup app developed by Veeam for virtual environments built on VMware vSphere and Microsoft Hyper-V hypervisors.[3] The software provides backup, restore and replication functionality for virtual machines, physical servers and workstations as well as cloud-based workload.[4]


Veeam Backup & Replication operates both the virtualization layer as well manages physical machine backup. It backs up VMs at the image-level using a hypervisor’s snapshots to retrieve VM data.[5] Backups can be full (a full copy of VM image) or incremental (saving only the changed blocks of data since the last backup job run).[6] Backup increments are created using the built-in changed block tracking (CBT) mechanism. The available backup methods include forward incremental-forever backup, forward incremental backup, and reverse incremental backup. Additionally, there’s an option to perform active full and synthetic full backups.[7]
Veeam Backup & Replication provides automated recovery verification for both backups and replicas. The program starts a VM directly from a backup or replica in the isolated test environment and runs tests against it. During the verification, the VM image remains in a read-only state. This mechanism can also be used for troubleshooting or testing patches and upgrades.[8][9]

Backup storage[edit]

Veeam Backup & Replication supports software-defined storage technology. It allows organizing a scalable backup repository from a collection of heterogeneous storage devices. Backups can be stored on-premises, transferred to off-site repositories via the WAN,[10] saved to tape media for long-term retention, or sent to cloud storage. Cloud storage support is available on an Infrastructure-as-a-Service (IaaS) model. Veeam's technology, Cloud Connect, provides integrated and secured backup to the cloud through Veeam-powered service providers.[11][12]
Veeam Backup & Replication is storage-agnostic, but it also has specialized storage integrations with some storage systems such as Cisco HyperFlex, EMC VNX, EMC VNXe,[13] HP 3PAR, HP StoreVirtual,[14], Nimble[15], NetApp[16], IBM[17], Lenovo Storage V Series[18]. In addition, through a separate Universal Storage API and plug-in, Veeam also provides storage integrations with INFINIDAT [19]and Pure Storage[20]. It uses storage system snapshots as a source for backups and recovery of VMware VMs with disks residing on storage volumes.[21][22]. Veeam Backup & Replication also have build in direct NFS agent which allows to access NetApp snapshots directly from NAS storage bypassing hosts for backup, restore & storage scan operations.


Along with backup, Veeam Backup & Replication can perform image-based VM replication. It creates a “clone” of a production VM onsite or offsite and keeps it in a ready-to-use state. Each VM replica has a configurable number of failover points.[23] Image-based VM replication is also available via Veeam Cloud Connect for Disaster Recovery as a Service (DRaaS).[24]


The software provides a number of data recovery options,[25] including:
Entire VM recovery:

  • An immediate restore of a VM via mounting a VM image to a host directly from a backup file (Instant VM Recovery)
  • Full extraction of a VM image from a backup

File-level recovery:

Virtual drive restore:

  • A specific VM hard drive recovery

Application-item recovery:


Veeam Backup & Replication decreases backup files size and data traffic with built-in data deduplication and compression. There is support for deduplicating storage systems such as EMC Data Domain,[26] ExaGrid[27] and HP StoreOnce Catalyst and NetApp Cloud Backup (AltaVault).[28] Using deduplicating storage appliances as backup repositories allows achieving greater levels of deduplication ratios. Veeam Backup & Replication also provides built-in WAN acceleration to reduce the bandwidth required for transferring backups and replicas over the WAN.


Built on a modular scheme, Veeam Backup & Replication allows for setting scalable backup infrastructures. The software architecture supports onsite, offsite and cloud-base data protection, operations across remote sites and geographically dispersed locations.[29] The installation package of Veeam Backup & Replication includes a set of mandatory and optional components that can be installed on physical or virtual machines.[30]

Mandatory components[edit]

  • Veeam backup server – a Windows-based physical or virtual machine where Veeam Backup & Replication is installed. It’s the core component responsible for all types of administrative activities in a backup infrastructure, including general orchestration of backup, restore and replication tasks, job scheduling and resource allocation.
  • Backup proxy – an appliance that retrieves backup data from the source host and transfers it to the backup repository offloading the Veeam backup server.
  • Backup repository – a primary storage for backup files, VM copies, and meta-data.

Optional components[edit]

  • Backup Enterprise Manager – a centralized management web browser interface intended for distributed enterprise environments with multiple backup servers.
  • Veeam Backup Search – an add-on to Microsoft Search Server for search performance optimization.
  • Standalone Console — a lightweight console for installation on laptops and desktops to enable the management of the backup server remotely over the network and eliminate RDP sessions to a backup server.[31]
  • Scale-Out Backup Repository — Since version 9 it's possible to build a flat backup repository space from a number of independent and non-clustered sources. This feature eliminates any need in a clustered backup namespace, now Veeam users to store older backups in more affordable storage targets.[32]


Veeam Backup & Replication is positioned as a part of the Veeam Availability Suite bundle (which includes Veeam ONE for monitoring, reporting, and capacity planning), but can also be installed as a standalone product. It is available in three editions based on the level of provided functionality. The product is licensed by the number of CPU sockets, or through annually or upfront-billed subscription licenses on a per-VM basis.
