shell scripts

It doesn’t matter what you’re running as CMS, forum or blog. Most software solutions are based on an Apache2 Server and a mySQL database. But only a few people are aware of appropriate backup solutions.

I hope below script will help people, who are not yet familar with rootserver, and are used to reinstall their systems (guess why I do know this ). Below two scripts will help you on creating a backup for your mySQL database and creating a dump of your whole web presentation files.

Below script will do the necessary BACKUP for you:

#!/bin/bash
# BACKUP SCRIPT FOR ROOTSERVERS
#
# ASSUMPTIONS:
# data stored in a mysql database (dumping and taring DB)
# webfiles (taring all webfiles)
#
# save this script e.g. web_backup.sh
# don't forget to chmod 700 web_backup.sh
# execute script via ./web_backup.sh
#
#
# DO NOT STORE FILES IN WEB ROOT FOR SECURITY PURPOSES!

Below script will do the necessary RESTORE for you:

#!/bin/bash

# RESTORE SCRIPT FOR ROOTSERVERS

# don't forget to chmod 700 web_restore.sh
# execute script via ./web_restore.sh
#
