Dell Replay Manager Version 7.8 Administrator’s Guide

Creating Backup Sets in a Hyper-V Cluster

Virtual machines may be moved among cluster nodes for a variety of reasons. Virtual machines may be moved manually, for example, in preparation for planned server maintenance. Virtual machines may also be moved dynamically, for example, when the Dynamic Optimization feature is enabled in Virtual Machine Manager. During Dynamic Optimization, the resources of each node in a cluster are monitored to optimize the placement of virtual machines initially and during failover.

In an environment where virtual machines move often within a cluster, and where collections of virtual machines do not consistently move together, each Replay Manager backup set should contain only one virtual machine per CSV. This avoids the need to frequently re-create backup sets to account for the movement of individual virtual machines.
