Paramiko’s SSHClient with SFTP

How I can make SFTP transport through SSHClient on the remote server? I have a local host and two remote hosts. Remote hosts are backup server and web server. I need to find on backup server necessary backup file and put it on web server over SFTP. How can I make Paramiko’s SFTP transport work with Paramiko’s SSHClient?
