Bash Server Backup Script

July 13, 2012

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:

# Backup Script purpose, to backup:
# 1. MySQL
# -create .sql and .xml dumps for each database separately
# 2. path's to log, http, etc, home, www
#
# Requirement: User must set values in section below

# How to use: Place script in cron to run daily
