My iphone starts syncing whenever I click on back up?

I'm trying to backup my iphone and i made sure it wasn't set on sync automatically but whenever i click on it it starts to sync. How can I make it just backup?

It has to sync to make the backup. It's literally making a copy of everything on the phone. Sync equals backup. ITunes will give the date/time of the last 'backup'. When you're happy with that, it's good. Best luck.
