Hyper-V Replication

Hardware failures, software bugs, human errors, and natural disasters can render your business-critical services or even entire datacenter unavailable. NAKIVO Backup & Replication provides a powerful way to recover from such failures.

The Hyper-V replication feature can create and maintain exact copies (replicas) of source Hyper-V VMs on a target host. The replicas are regular powered off VMs, which don’t require any compute resources. In a disaster situation, you can simply power on the replicas for near-instant recovery.

Hyper-V Replication Features

Application and Databases Support

Application and Databases Support

Since applications and databases constantly process data in memory, it is not enough to just make a copy of the data stored on disk. NAKIVO Backup & Replication provides the Application-aware mode, which ensures that applications and databases such as Exchange, Active Directory, SQL flush the data from memory to disk before a replica is made, thus ensuring that replicas are application-consistent.

Forever-incremental Replication

Forever-incremental Replication

All VM replication jobs are forever-incremental, which means that only initial replication creates a complete copy of a source VM.

Later on, the product detects changed blocks of data (increments) and merges them with the VM replica, leaving the previous state of the Hyper-V VM as a new recovery point.

Flexible Recovery Point Retention Policy

Flexible Recovery Point

NAKIVO Backup & Replication can save up to 30 recovery points for each VM replica, and you can use Grandfather-Father-Son (GFS) scheme to rotate recovery points on a daily, weekly, monthly, or yearly basis. Recovery points are regular Hyper-V VM snapshots, so you can roll back to any recovery point even without NAKIVO Backup & Replication.

Staged VM Replication (Seeding)

Staged VM Replication

Initial Hyper-V replication may be time and bandwidth consuming because a VM itself might be huge. To speed up this process and offload your network, you can perform a staged replication. This means that you make the initial VM replication onto a removable media, and then move those replicas to a new location.
