HYCU – Backing up virtual machines from Replicated Nutanix Snapshots

In remote office/branch office (ROBO) environments, HYCU allows you to back up virtual machines from their replicas on the central site Nutanix cluster. Backing up data from replicas without having to transfer the virtual machine data twice frees up WAN bandwidth for other business processes.

To be able to back up virtual machines from their replicas, make sure that the replication retention on the Nutanix cluster is adjusted to the backup policy’s RPO. This allows HYCU to use the Changed Region Tracking (CRT) feature to get a list of changed data since the last snapshot and perform an incremental backup. For example, if the Nutanix schedule interval is two hours and the RPO of the HYCU backup policy is eight hours, the retention policy for the remote site must be set to 4 or more snapshots (that is, at least the last four snapshots must be kept).
