# REQUIREMENTS
###########################
#
#   * Required commands:
#       + mysqldump
#       + du
#       + bzip2 or gzip     # If bzip2 is not available, change 'CMD_COMPRESS'
#                           # to use 'gzip'.

#
#   * It stores all backup copies in directory '/var/vmail/backup' by default,
#     You can change it in variable $BACKUP_ROOTDIR below.
#
#   * Set correct values for below variables:
#
#       BACKUP_ROOTDIR
#       MYSQL_USER
#       MYSQL_PASSWD
#       DATABASES
#       DB_CHARACTER_SET
#       COMPRESS
#       DELETE_PLAIN_SQL_FILE
#
#   * Add crontab job for root user (or whatever user you want):
#
#       # crontab -e -u root
#       1   4   *   *   *   bash /path/to/backup_mysql.sh
#

#       # ---- On RHEL/CentOS ----
#       # chkconfig --level 345 crond on
#       # /etc/init.d/crond status
