Copy email to flash drive

I want to save my old Evolution emails and calendar, then do a clean Ubuntu reinstall of 9.04 and restore the old emails and calendar..There's a good how-to at "copy email files to flash drive," Question 36491, from Andre Mangan on 6/17/08. It's below. My questions are: (1) This will copy my calendar too, right? (2) There's nothing in my ~/.gnome2_private/Evolution file. Is that unusual?

   1. Create a file in your Home directory and call it Evobackup
   2. Transfer the following files:
      a) ~/.evolution/
      b) ~/.gconf/apps/evolution/
      c) ~/.gnome2_private/Evolution

gconftool-2 --shutdown <Enter>
evolution --force-shutdown <Enter>

cd <directory> if you called the newly created file Evobackup, then the command would be
cd Evobackup <Enter>

tar -cvzf Evobackup.tar.gz .evolution .gconf/apps/evolution .gnome2_private/Evolution <Enter>
This will create a file called “Evobackup.tar.gz”. Save that file to a USB stick.

To untar the file Evobackup.
Open the file from your USB stick and save it into your new Home folder on Hardy Heron.
In your home directory use the following commands from a terminal:
gconftool-2 --shutdown <Enter>
evolution --force-shutdown <Enter>
tar xzf Evobackup.tar.gz <Enter>
gconftool-2 --unload evolution_se <Enter>
gconftool-2 --load evolution_sett <Enter>
When you start Evolution in Hardy it will ask you if there is anything to restore and it will ask you for the
path to the restore file. Just follow the prompts.
