When Veeam Backup Server is backing up with SQL Server, SQL Server will send packet port 445 from Veeam Backup Server. What is the problem and how to solve it?

Port 445, or SMB, is used to transfer the guest processing runtime/components from VBR to the SQL-Server. Take a look at this page from the helpcenter:

Those drops only appear while the backup is running?
What kind of backup job have you configured and what are you using as a target backup repository?

Unfortunately I don’t have an idea why the guest VM would connect to the VBR server via SMB. Maybe you can find any hints in the Veeam Guest Processing Logs on the SQL server itself; %PROGRAMDATA%\Veeam\Backup
If not, I would suggest to open a case and let support check your configuration.
