we need to backup some database in a unc path, the problem it's that it's an sql instance that have to execute with sql autentication (sa user). How can we configure the plan task in SQL to make it able to have access to the unc folder? I attach the state of our SQL Server Services in "SQL server configuration manager".

Thanks in advance and regards,
