#
# fullsitebackup.sh V1.1
#
# Full backup of website files and database content.
#
# A number of variables defining file location and database connection
# information must be set before this script will run.
# Files are tar'ed from the root directory of the website. All files are
# saved. The MySQL database tables are dumped without a database name and
# and with the option to drop and recreate the tables.
#
# ----------------------
# March 2007 Updates
#    - Updated script to resolve minor path bug
#    - Added mysql password variable (caution - this script file is now a security risk - protect it)
#    - Generates temp log file
#    - Updated backup and restore scripts have been tested on Ubunutu Edgy server w/Drupal 5.1
#
#    - Enjoy!  BristolGuy
