# RSYNC is a software application for Unix systems which synchronizes files and directories from one location to another :::

#  IMPORTANT : add your own data or parameters, I make use of double segments [[ your variable ]]. eg. ssh root@[[ 96.172.44.11 ]] should be replaced with ssh root@888.88.88.88 where "888.88.88.88" is your value, variable etc. I have a habit of using ":::" to indicate line ending and end of paragraph, crazy I know but be warned its just how I write ::: All notes are for my own use & should you use any it's at your own risk, it's NOT a Tutorial :::

# Backing up files can be simple like my example below, or a bit more complicated backing up with RSYNC to another server etc. I did not need anything "complicated" but if you require exteral sync, below are several links to get you going :::

# If you get an error like this : line 8: $'\r': command not found ,  you have CRLF line endings (that's \r\n in C and related languages).
# The simplest is to install dos2unix
sudo apt-get install dos2unix

# Then run
sudo dos2unix /var/www/[[ yourdir ]]/bu-wp-content.sh
