# Joachim van de Haterd, november/december 2006
# JH: Version 2 was written July 2007
# JH: Version 3 was written March 2011. The old disk has been replaced with a more modern container.
# JH: Version 3.5 was written April 2014. Some stuff is being backed up to and from my NAS as well.

# Checks whether an external partition was mounted
# and rsyncs both /home and /etc subdirectories.

# See https://github.com/derjoachim/joatools for more information

# @TODO:
# - Put all subdirectories to be excluded into an array. This makes the script more configurable.
# - Formerly, the rsync command for /home was called with sudo. Not sure why needed. Have to check whether still necassary.

# @Param a) Disable automatic mounting / unmounting
# @Param d /dev/partition) Manual path to HDD device
# @Param h) Show a more helpful message and exit gracefully
# @Param n) Chicken mode: do not do anything. Only show what would be done if you had shown some guts. :)
# @Param u) Disable automatic unmounting. Keeps truecrypt volume mounted upon exit.
