HI what I ended up doing was rolling back to a previous kernel version on Bacula VM and that resolved the issue, still trying to figure out what in the kernel update could have caused the issue.

I'm late answering this, but I suggest trying again with some TCP offloading features disabled on the interface used by SD. /sbin/ethtool -K ethX tso off gso off gro off There are indeed buggy drivers that fail to properly support the (virtual?) hardware offload features, including at least some version(s) of virtio-net, as I discovered and wrote about in my August 5 2020 post here. Keep in mind that Bacula, of necessity, taxes the network for long periods of time, often for hours. It reveals network issues that a few seconds or minutes of iperf cannot. (In fact, I think virtio developers should consider using bacula-fd in a VM in their destructive/performance testing.)

The linux backups are running well, with almost gigabit speeds as we have a gigabit backbone network. But then windows backups are extremely slow averaging around 65kbps. I have tested the network connectivity between the backup server and clients using iperf and there is no issue there I see speeds of over 700mbps. I have also tried disabling VSS and enabling Spool Data but no change. I have also tried the Maximum Network Buffer Size = 32768 on the client but still no change. There is no firewall running on the windows machine. > > Has anyone seen this any help is greatly appreciated. > > Thanks > Satvinder > > Disclaimer: This message is intended only for the use of the individual or entity to which it is addressed and may contain information which is privileged, confidential, proprietary, or exempt from disclosure under applicable law.
