Totally noob question:

I just moved from thunderbird to evolution, I wanted something better integrated with the desktop (running lucid, evolution 2.30.3). I know that to backup evolution settings (mail, contacts, calendar, etc..) you go to file ->backup settings. My question is: does it also backup contact pictures? what about birthdays on calendar? and how can I get it to backup all my mail, including IMAP mail?

thanks for the help
