Backup fails, no proxy available

D
Userlevel 2

Hi, I’m trying to back up a VM running on a standalone ESXi v8 host using Veeam B&R v12 Community edition.  When I set the job up it ran successfully but all subsequent (scheduled) backups fail with “Failed to create processing task for VM Sophos Firewall Error: No proxy available”.

If I edit the job without changing anything (just applying the same settings) it will run.  Also, if I do the same with the VMWare Proxy object or the veeam server object (in Backup Infrastructure > Managed Servers) it will also run.  In all cases it will only run the first time after applying the settings. Again, all subsequent runs fail.

The veeam ‘server’ is an i3 8GB Windows 10 22H2 x64 PC.  What looks to be the root cause is an entry in the job backup log that says:

[ProxyDetector] VMware host API version is V800. Skipping not x64 proxies
[ProxyDetector] VMware host API version is V800 and all available proxies are not x64 so we can not use it with such API version

I’m not sure what to do with this; Where do I get the x64 VMware proxy from?  I assumed the installer would install the bitness version that matches the OS, and the OS is definitely x64.  I also don’t understand why it works on the next backup after modifying any of the components, but not subsequent runs.

Thanks in advance.

Not sure why this would fail based on your OS for the Veeam server but do you have a Windows machine on the ESXi host that is x64 that you could add as a Proxy and see if that helps?

Further to what @Chris.Childerhose mentioned, are you using a particular transport mode? 
Are you able to provide any screenshots of the settings and error messages?

Hi @dav.san - though documentation supports Windows 10 OS as a host for VBR and being used as a Proxy, there was a known issue noted in the forums, specifically with Win7/8, which seemed to also affect Win10, which may be what you’re running into. Not exactly your error, but may be related a bit. Also, it seems someone else posted here in the Hub who ran into a simiar issue, tho their problem was related to Win2022 Server. 

I didn’t really see much anywhere posted about this error searching the Internet. Aside from trying what Chris suggests (creating a Windows or Linux VM to use as a hotadd transport Veeam Proxy), and seeing if that works better for you, I can only suggest contacting Support to see if they’ve run into this & if there’s a fix.

Thanks both for responding.

I don’t think the ESXi host has enough resources for a Windows VM, it’s one of those fanless PCs that look more like a giant heatsink, so resources are plenty for SF, but not much more I’m only running ESXi on it because Sophos Firewall doesn’t recognise consumer 2.5Gbe NICs natively, so have to run it as a VM. (my original intention with this PC was to run it natively)

Using Network transport, manually selected in the Proxy.  Auto throws the same error.

I’m backing up to an iSCSI target on my NAS, mapped to the Veeam server on drive F:

Incidentally, I’ve also wiped and reinstalled Win 10 x64 from a new installer that only had x64 installation media on it.  This is also the part of the log that mentions bitness:

Did you use ‘Automatic Selection’ as your transport mode previous to configuring/testing Network mode? Does using Automatic give you the same result?

Nothing really stands out from your logs. Only suggestions I can offer is attempt to add a x64 Windows or Linux virtual machine as a Proxy to your VBR server and use it for your job to see if you have better success, and/or contact Veeam Support. They do support free Community Edition.

It’s not free version of ESXi is it? As that’s not supported as per the help centre as the api’s needed are disabled.

@MarkBoothman No, it’s licensed through work for my lab. 

Didn’t realise that Veeam support the community edition, pretty sure they say on the download page that they don’t, but I’ll give it a shot.

Are there any guides on setting up a new server as a proxy, as I think that’s also worth a shot and I didn’t realise you could offload components to other servers.

Thanks everyone for your responses, didn’t expect anything so quick!! 😀

For a Proxy, just create a basic Windows/Linux VM on your Host. Then, on your VBR server, in Backup Infrastructure node, rt-click Managed Servers > Add Server & select Windows/Linux. Just go through the brief wizard. Next, go up to Backup Proxies, rt-click > Add Proxy > VMware Backup Proxy, and go through the wizard. In your Backup job, rt-click > Edit it and under the Storage option, choose your new Proxy. Re-run your job and see if it works for you.

Just adding an update to this in case anyone else comes across this issue;

I installed the hyper-v role onto the veeam server and set up a slim CentOS 7 VM.  Added it to the managed servers list and then created a new VMware Proxy using this VM.  All as suggested by the helpful people above.  Many thanks to them.

Worked a treat.  Manual backup and the scheduled backup completed successfully.

 

Now…. as any IT Pro would feel, this is great, but I still want to know why the veeam server isn’t working as its own proxy, if indeed it should….. 🤔

It might be worth logging a ticket with Veeam Support and see if they are able to provide an insight into what might be causing the issue.

Based on the errors posted did you check your proxy servers?  It seems like there is not a proxy that can communicate with the VMware API to complete the backups.

I had a string of issues like this and decided that Veeam was just too flaky and unpredictable so ended up ditching it.  I only need to back up a small home lab so now use Aomei Cyber Backup.  Definitely not a commercial grade product but for home use it’s simple, doesn’t need “proxies” and reliable. Backs up ESXi VMs no problem and without an agent, so was fine for me.

Hi

 

There is prosxi that it added when adding vcenter

 

I also did not add a prosxi.

 

It has worked like this for 3 years without any problems, but it started giving errors 2 days ago and we could not figure out the reason.

What version of Veeam are you using?  Did you check the logs to see if there is any other messages to help - C:\ProgramData\Veeam\Backup

Other than that a support case might be needed to further troubleshoot.
