LAN-Free Data Transfer

Separate backup and replication data streams from your production network. NAKIVO Backup & Replication reads the VM data directly from a SAN storage device or the VM datastore to speed up your data protection workflows and offload the LAN. The LAN-Free Data Transfer feature allows you to reduce the impact of backup and replication activities on your business-critical operations.

LAN-Free Data Transfer in NAKIVO Backup & Replication

Use LAN-Free Data Transfer for VMware vSphere VM, Microsoft Hyper-V VM, and Nutanix
AHV VM data protection activities. NAKIVO Backup & Replication automatically runs
workflows in the Direct SAN mode or the HotAdd mode if a SAN isn’t available.

In the direct SAN mode, VM data is transferred directly from the SAN storage device.


The HotAdd mode is automatically enabled when you don’t use a SAN storage device. In this mode, NAKIVO Backup & Replication reads the data directly from the VM datastores and mounts (hot-adds) a VM snapshot as a virtual disk. The VM data is transferred through the storage I/O stack and doesn’t pass over the network or through the VM host. As a result, you can achieve almost the same performance as with the Direct SAN mode.

Direct SAN access

If you use a Storage Area Network (SAN), NAKIVO Backup & Replication reads the VM data directly from SAN storage devices over ISCSI or Fibre Channel. In the direct SAN mode, the data doesn’t pass over LAN or through VM hosts. This way, you can achieve higher data transfer rates without putting an extra load on the
production network.

In the HotAdd mode, VM data is transferred directly from the VM datastore.
