Poor Veeam restore performance
I'm restoring a VM backed up with Veeam B&R v6.1.0.181 from a virtual machine on an 8gbit FC san. The vm is restoring to a host outside the cluster, but inside vCenters scope. The Host is on the same cisco 3650 1gbit switch.
My restore rate is betwen 7MB/sec and 22MB/sec. This seems extremely slow. The VM running Veeam has 4GB of vRam and 2 vCPUs. I'm unable to find a bottleneck using any reporting or performance graphs.

Hi Marcel,
Could you please tell me what performance rates you have while uploading files to the same datastore with vSphere Client?
Thanks!

Re: Poor Veeam restore performance
Approx 2MB/sec while Veeam restore job is running via vSphere. vSphere is measuring a peak network transfer rate of 60Mbps.
Approx 2MB/sec while Veeam restore job is running via SFTP. vSphere is measuring the same peak network transfer rate of 60Mbps
The Datastore is local to the non-cluster host.
There are no other VM's running on that host to test VM to VM network speeds.

Re: Poor Veeam restore performance
Are you running the restore through hot add backup proxy?
Also, are you possibly confusing products (Veeam does not support SFTP).

Re: Poor Veeam restore performance
Try deploying Veeam backup proxy on the host you're restoring the backed up VM to. In this case the restore process will go via HotAdd mode, which should give you better performance rates compared to just network restore.

Re: Poor Veeam restore performance
Are you suggesting that I purchase an additional Windows Server license for every host in my organization to improve backup rates from 7-22MB/sec?

Re: Poor Veeam restore performance
You can simply re-use any existing Windows VM as backup proxies, or alternatively use instant VM recovery to bring the VMs back and then migrate them to production datastores. Network restores cannot go faster than the upload performance via vSphere Client.

Re: Poor Veeam restore performance
I just deployed an OVF at an average of 62MB/sec. This is approximately 3-8X faster than Veeam restore speed.

Re: Poor Veeam restore performance
Yes, there are more efficient data movers available in ESXi. Unfortunately, VMware does not make all existing internal APIs available to vendors. As such, we are limited to transport modes provided by VMware vStorage API (VDDK).
However, when VM recovery speed is important, Instant VM Recovery beats even those advanced transport modes big times.
