Slow backup performance when the owner of VM and CSV is not same

[kf2013]

3 hosts in the Hyper-V 2012 cluster and few CSV volumes.

The slow backup performance (around 1xxx MB/min in backup exec) will occure when it meets the following scenario :

1. VM on Node 1 and CSV 1

2. CSV 1 owner is Node 2

When i change the owner of CSV 1 to Node 1, the backup performance will return to normal (over 6000MB/min in Backup exec).

...make sure that the hardware configuration on the 2 hosts is the same (ie. all NICs set to 1GB FULL), and that any AV installed isn't actively scanning the BE services on the host giving slow performance.

Thanks!

I don't think the problem relates to the hardware configuration. Because when i change the owner of CSV to same node as the owner of VM, the backup performance will return to normal (around 6000MB/min).

I would recommend to log a formal support case so that we review the setup and possibly, debug logs as well.
