Backup server - Software layout

Hmm... Getting a transfer speed of 127 MB/s and a transfer speed of 108 MB/s. This is transferring over the network from HV host 1 to this new backup VM on HV host 2.
Anyone with a similar setup? Curious as to what speed others are getting on their backups.

@fuznutz04 You can't expect more if you have mechanical harddrives in RAID 1 or just 1 gigabit NIC.

That sounds like your device limits, as Pete pointed out.

That's exactly what I have. I suppose I could bond some NICs together, but I'm sure the drives are the limiting factor. At this point, for my backup volume and large backup window, it's fine. But maybe if I get a chance, I'll do some testing with bonding NICs just to see.

I set up Switch Independent teams on all hypervisors always.
You can only get single link max on any given connection, but backup software usually uses multiple threads. SO you can max out multiple links like that.

Might be the beer talking, but when you say "Switch independent", do you mean team the nics together with the NIC driver/software before presenting it to Hyper-V, or am I way off?

Way off.
The terms vary, Microsoft calls it Switch Independent mode.
Linux (Fedora) calls it load balancing.Basically, it is not LACP bonding.

I also never use the NIC software.
I only ever use the OS to make teams.

Well then, looks like I'll start googling

I use teams, even if there is only one NIC in the team most of the time, because I can add and remove NICs without impacting the higher layers.

Good idea. This server I just got has the onboard GB NICs, but also 2 dual port Intel GB NICs as well. I could create a BIG team if I wanted.
