How Backup Works

While creating image-level backups, Veeam Backup for Nutanix AHV does not install agent software inside VMs to retrieve data. Veeam Backup for Nutanix AHV uses native Nutanix AHV capabilities to take VM or protection domain snapshots and produces backups in following way:

  1. The web console sends the backup job configuration data to Nutanix AHV backup appliance.
  2. The Nutanix AHV backup appliance starts a backup job and forwards the backup session data to backup server.
  3. The Nutanix AHV backup appliance connects to the Nutanix AHV cluster over Nutanix REST API and creates backup snapshots of all VMs or protection domains added to the job.
  4. The Nutanix AHV backup appliance creates a volume group on the Nutanix AHV cluster.
  5. The Nutanix AHV backup appliance launches a worker and mounts VM disks to the worker over iSCSI.
  6. The worker retrievers VM data on the block level.
  7. The worker compresses and deduplicates the data and forwards it to the backup repository in the native Veeam format.

Note

To limit the impact of backup tasks on network performance, Veeam Backup for Nutanix AHV applies network traffic throttling rules that prevent jobs from utilizing the entire bandwidth available in your environment.
