How to backup local system to a remote machine via ssh?

How do I use rsnapshot to backup my local system to a network machine to which I can ssh via ssh me@backupmachine?

I edited /etc/rsnapshot.conf but no luck:

• I tried to set snapshot_root me@backupmachine:/home/me/backup but that did not work.
• Then I tried setting backup: backup /home/mydir/ me@backupmachine:/mydir, that also did not work.

Is this possible at all?

p.s. All permissions are set, it's just that conf file is not doing what I would expect.
