Sophos blocking Veeam Agent on Windows 11

Hi Tony,

Thanks for reaching out to the Sophos Community Forum. 

Could you let me know if any errors are shown in Veeam or if the backup operation continues running without completion?
Are both devices on the same local network such that the allowed/blocked domains and ports are the same? 

As an initial check, I'd suggest checking that Veeam's suggested exclusions are added to Sophos.

I am not getting any errors logged anywhere. Both devices are on a local network, the same as the third machine that is working. I would add the exclusions but as I stated I am new to Sophos and do not know where to add those exclusions. Thanks.

**UPDATE** I was able to get the job working by assigning a Windows Firewall Policy in Sophos Central. However, it is an 'Allow All' policy as I do not see any fine grained options.

In your case, a "Process" exclusion may be best, as this will exclude the file and network operations that the given exe performs. Checking the Veeam documentation available, I was not able to locate any exe's referenced specifically. 

When you trigger a backup, could you try checking Task Manager to see what processes start on the device? Linked below is more information on:
