#   that this script will not do irreparable harm to your host if you
#   use it.

# MAKEFILEBACKUPS will back up the FILES from the folders above if it is set to 1.
# This will take time and space.  If you have, for example, an uploads folder under

# space and that can crash your site.  That's why this step is off by default.

# MAKESQLBACKUPS IS NOT YET RELEASED.
# MAKESQLBACKUPS enables Database backups to be made of the WP specific tables
# for each blog.  It reads the database username, password and table prefix
# It is disabled by default for several reasons
# 1. Copies of a DB on a webserver is a security risk
# 2. I suspect it will not work on all systems mysqldump must be present
# 3. Your wp-config file might not allow me to read it
# 4. Your wp-config file might customized in a way I cannot predict
# 5. I'm not done testing it
#MAKESQLBACKUPS=1   # CURRENTLY THE SCRIPT WILL NOT BACKUP YOUR SQL
