we have a Hyper-V Cluster with two hosts.
The backup job is defined to save all vms through the "cluster-hostname" (cluster ip) backup host.
The cluster ip can only be on one host at the same time and switches to the other node, if you restart the host where the cluster ip is currently deployed.
Since DP is only backing up vms directly over san where the cluster ip is located, all other vms which are located on the second host need to be sent through lan to the backup host, and so a bottleneck is created.
A few days ago i migrated all vms to the host where the cluster ip is deployed to see how much the time difference would be and the difference was huge. If all vms are on the cluster ip node, the backup job would only need around 8 hours, else if all vms are distributed on both nodes evenly it takes around 15 - 20 hours depending on where the vms are located.
So my question is, is there a better way to backup my vms and save time?
