Bash Server Backup Script

I’ve created a Bash Server Backup Script that will backup your MySQL databases (each database separately in to .sql and .xml files) and your main directories (/var/log, /var/www/html, /etc, /home, /root) to a timestamped directory. Feel free to re-use or hack up however you’d like

Here’s my Bash Server Backup Script:
