Veeam Backup & Replication is a proprietary backup app developed by Veeam Software as one of their first widely adopted initial products, ultimately expanding beyong the Foundation pillar (VBR) of the Veeam Data Platform ^[1] ). Initially designed with Physical and Virtual Environments (e.g. Hypervisors, HCI, KVM's, etc; Most notably as of 12.3 includes VMware vSphere, Nutanix AHV, KVM's and Microsoft Hyper-V among others. The software platform support has expanded and provides backup, optional malware detection scans during backup, restore, replication/CDP, and much more functionality for virtual machines, physical servers, workstations as well as cloud-based workloads and unstructured data.

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. 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). 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 is an option to perform active full and synthetic full backups.
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.

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, 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.
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, HP 3PAR, HP StoreVirtual, Nimble, NetApp, IBM, Lenovo Storage V Series. In addition, through a separate Universal Storage API and plug-in, Veeam also provides storage integrations with Infinidat and Pure Storage. It uses storage system snapshots as a source for backups and recovery of VMware VMs with disks residing on storage volumes. 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. Image-based VM replication is also available via Veeam Cloud Connect for Disaster Recovery as a Service (DRaaS).

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

File-level recovery:

Virtual drive restore:

Application-item recovery:
