I upgraded to Veeam 13 a few weeks ago.   I finished adding my 2.5G network and VLANs on Thursday.   My Ubuntu 24.04 servers are backing up fine.   Veeam 13 in my workgroup wants certificates now.  I had to spin up a Windows 2022 Standalone CA to create certificates for all Windows 10 and 11 workstations.   I will be creating the workstation certs from it today and installing them.   Any suggestions on getting Windows 11 to backup?  I hope the cert does the trick.  

2.5G network is much faster.  I will post numbers tonight.

@SCSIraidGURU ...are you saying since upgrading to v13, your Windows devices aren’t backing up? I assume physical devices? (agents) Or, are they VMs?

I am using Veeam 13 in my homelab with Agent backups and did not have to do a CA for certificates.  Now I do have a CA, but that is for other things and never had to do anything with my systems to get backups to work properly.  This is not a hard requirement that I am aware of.

I had to redo the Veeam certificate and fix the Win10x64i7/Admin$ link.  Options - Security - Regenerate the Veeam Cert.    I upgraded the NICs to 2.5G and everything changed.

Here are the numbers for the 2.5G upgrade.  I run the VMs, FamilyPics, and Dropbox at the same time. 

 

  1 Gbps 2.5G
Windows 11 58 min 37 min
Dropbox 66MB/s 162MB/s
FamilyPics 109MB/s 139MB/s
VMs 219MB/s 328MB/s

Ah, ok, so more on the VBR side. Interesting changing a nic broke the Veeam Cert. 🤔

Those are some nice improvements for speed of backups. 😎
