Evolution Mail backup.

#!/bin/bash
# Filename: evo-backup.sh
# Version: 020112
# Author: robz
# This script creates an encrypted archive of all the relevant Evolution Mail
# directories and preferences to act as a backup to said program. Now I know
# Evo already provides a backup feature but AFAIK it isn't automateable and
# doesn't encrypt. You will need to modify your Evolution launcher/s path/s to
# point at this script instead of just "evolution"
# If you have sym/hard links to your Evolution directories "tar" will follow
# them, "find" however is not setup this way, you'll need the -L option if the
# path to your backup directory uses links. see "man find"
# You're required to have a personal gpg key setup, see "man gpg" or goto menu:
# System > Preferences > Encryption and Keyrings and create one for yourself.
# I would strongly suggest you do a manual Evolution generated backup before
# running this script, as insurance, what works for me bla bla bla :)
