We are using Veeam Backup and Replication 18.104.22.1683 (Free Edition) to backup Hyper-V VMs but the backup jobs are extremely slow, the processing rate is 1 MB/s.
The Bottleneck is showing: Source: 4%, Proxy: %6, Network: 99%, Target: 0%
We are facing this issue on both Hyper-V servers we have, the backup target is C:\Backup
Veeam is installed on ESXi VM, we have tested the network speed between the Veeam server and the Hyper-V multiple times, all network SMB tests are showing network speed of 60+Mbps on write and read.
What could be the issue? if the network speed is fine why would the bottleneck be Network, during the backup process the speed is getting as low as 500 KB/s. The backup job of VM having 34GB as used space is taking almost 4 hours to complete!
Thanks in advance.
