Slow Backups of non-Cluster Host Servers

Post by bdearlove »

Good Day All,
Giving Veeam a test and think I have something setup incorrectly. Running a Hyper-v 2 Node cluster with SAS shared storage (Dell MD3220 SAS). When backing up VM's from the CSV backups of guests on the non-cluster Host Server speeds are half of what they are (usually around 50 MB/s as opposed to 100MB/s) on the Cluster Host Server. Is this common or something I may have easily set up wrong? Thanks!

So you have 2 hosts in cluster, and 1 standalone?
What storage the standalone host is using?

Sorry, no, 2 hosts in a cluster, 1 physical server running veeam with local storage. Backing up guests on the cluster master is twice the speed of the other cluster member. If I make that host the cluster master guest backups on it are twice the speed.

Hyper-V 2012, it looks as though the backups are fast one the CSV Owner Node, and half the speed on non CSV Owner Nodes.

Ignore my silly question, answer is redirected mode!

This is why I asked about Hyper-V version. Basically, what you have referenced does NOT apply to Hyper-V 2012. In other words, redirected access should never happen. I will ask devs if they have any thoughts, but most likely they will request that you open a support case and provide all logs.

Thanks. I have contacted Dell also to see if it is an issue with their storage as I can replicate the issue on two MD3220 SAS storage arrays.

Kindly please update the topic with Veeam support case ID once you open a support case. Thanks!
