Veeam Backup & Replication lets you perform onsite replication for high availability scenarios and remote (offsite) replication for disaster recovery scenarios. For more information, see Changed Block Tracking. To keep track of changed data blocks, Veeam Backup & Replication uses different approaches. Veeam Backup & Replication copies only those data blocks that have changed since the last replication job session. All subsequent replication cycles are incremental. Unlike backup files, replica virtual disks are stored decompressed in their native format.

Veeam Backup & Replication uses this point-in-time copy as a source of data for replication.ĭuring the first replication cycle, Veeam Backup & Replication copies data of the original VM running on the source host, and creates its full replica on the target host.
When you replicate a VM, Veeam Backup & Replication instructs Microsoft Hyper-V to create a cohesive point-in-time copy of a VM. To replicate VMs, Veeam Backup & Replication leverages Microsoft VSS snapshot and checkpoint capabilities. Replication provides minimum recovery time objective (RTO) in case a disaster strikes because VM replicas are in a ready-to-start state. Veeam Backup & Replication maintains this copy in sync with the original VM. When you replicate a VM, Veeam Backup & Replication creates an exact copy of the VM in the native Microsoft Hyper-V format on the target host. Replication is a technology that helps you protect mission-critical Microsoft Hyper-V virtual machines.
