SQL backup from local machine to internet server

I have MS SQL server on local machine without internet connection (server 1). I have urbackup client in same local network but have internet connection (server 2). Can I backup base from server 1 through server 2 and send on urbackup server on internet?

Eeh, it might be a bit of a strange setup. But you could use SQLCMD to make a export/backup of the SQL databases on server 1 and have it store those backup files on a folder on server 2. When server 2 is then backed-up to the online urbackup server, it will take the sql backup files from server 1 with it.
