What is the last version of VEEAM Backup Community Edition to support Windows 10 or 11 ?

I’d be curious what ISP.  I have up to 12 test versions of server os’s running in esxi or proxmox at any given time.

You can use the latest 12.3 release as it is supported on Windows 10/11.  Check here - System Requirements - User Guide for VMware vSphere

How is your ISP aware of what OS you’re using? I’ve never heard of that happening, I’d love to know more about why that happened.

To answer your question directly, the latest release of Veeam version 12 is supported on Microsoft 10 and 11.

+1 on what your ISP is seeing. I run 2 instances of Proxmox and have several VBR Servers at home in my lab. I also back up my entire network (well, what I can). your ISP shouldn’t have any say in this if you are internal to your own network. 

. Their residential service terms of service (TOS) are designed for typical home use, not for hosting servers that provide content or services to people outside your local network

Xfinity:

Examples of prohibited equipment and servers include, but are not limited to, email, web hosting, file sharing, and proxy services and servers;

My wife works from home.  She is a web programmer for news paper parent company.  I don’t want to risk having my internet down for a few days because I installed a server.  

VEEAM 11 works on Windows workstation.   I saw that they dropped support on VEEAM 13.  

Yes there were many things deprecated in Version 13.  See this forum post - [V13] Deprecated and Discontinued features for our 2025 release - Page 2

I guess I will be able to get to VEEAM 12.3 CE.  It has Proxmox VE support.  VMWare 6 support.   I recommand VEEAM CE to my tech friends online with home labs.   Not sure what happens when 12.3 disappears.  

Then you need to upgrade technology with it.  😂

Home ISPs have rules against running Windows Servers.   I will check with ATT Fiber and Xfinity to see if I can run a Windows Server for VEEAM backup within their policy.   Last time I tried, I was offline from the internet for 3 days after I shut it down.

Don't expose your server publicly. 

If you are trying to back up resources within your home network anyway, it shouldn't need to be public. 

I have a Fortinet 61F firewall with SD-WAN.   ATT Gigabit Fiber 1020 up/down and Xfinity 1100 Down/50 up at home.   Two Fortinet WAP units connected to the 61F.   My home is well protected.  I backup my VMs and workstations to VEEAM.   My home lab is better than most small businesses.

Looks to me like the issue is your server is public facing. Running a server is not a problem. Running your server public facing is the problem. That is two different things. I’m curious why you are exposing it to the public? For a home network/lab, I wouldn’t expect it to be public. Keep it behind your firewall and not exposed and you should be fine? Seems simple enough.

When I lived in Florida, I was on Xfinity. I ran multiple Server OSes without issue. Nothing was public facing though because it wasn’t necessary.

All my servers are behind the Fortinet 61F firewall.   They get their updates and security patches from the internet.  VEEAM Community Edition was put on Windows 7 to 11.   It allowed home users the availability of backups for free.   I added tape drives to protect my data at home.   I just put in LTO 4 drives last year.   I am looking at refurbished LTO 5 drives.   

How do you get patches for your servers.  Xfinity gateway is Swiss cheese.   It can be hacked with little trouble.   Aren’t you worried about it?  Xfinity has bot net issues all the time  

Home ISPs have rules against running public servers, not against running servers in general.  You even quoted the relevant section of the rule: “...provide network content or any other services to anyone outside of your Premises local area network (“Premises LAN”), also commonly referred to as public services or servers.” (emphasis mine)

If your home servers are truly behind a firewall, then the ISP should not be able to see what OS you’re running.  The fact that you download Server updates doesn’t prove anything.  I have a physical Windows 2019 server and a virtual (VMware Workstation) Windows 2025 server running at home with access TO the Internet - but no access from the Internet - and AT&T hasn’t said a word.  When I had Comcast, I ran multiple servers and had no issues.

But if the ISP thinks that your servers are public, you may want to check your firewall rules.

I run multiple Windows Server VMs in my homelab without issue for my ISP - I just don’t expose them externally.  Windows updates also run without issues.

On the fortinet 61F, to expose a server to the outside world, I need to create VIPs (Virtual IPs).  I have them for my web server and my children’s Minecraft servers.  I used the allow_user in Minecraft to control who can play.  I also change the port of the server.  I was going to try to upgrade the VEEAM server to Windows 10 or Windows Server equivalent.   The hardware is old.  I know Windows 10 will work on it other than the SCSI 39320 adapter.  I am looking to replace the LTO 4 drives.  I have 3.  Two SAS and once SCSI.
