Fullsiterestore

While looking for a quick and reliable way to get complete working backups, I stumbled over these shell scripts. They were originally designed for Drupal, but can easily adapted for use with MediaWiki.

Fullsitebackup creates a complete backup of the files of an MediaWiki installation and of its database. Fullsiterestore restores both. Also, the scripts can be used to migrate an MediaWiki installation from one to another host.

Please note that these scripts have some limitations, have some security risks, and are not tested thoroughly.

To do: Testing; handling of charsets; handling of innodb tables and lots more.

#!/bin/bash
#
# fullsiterestore.sh v1.1
#
# Restore of website file and database content made with full site backup.
#
# A number of variables defining file location and database connection
# information must be set before this script will run.
# This script expects a compressed tar file (tgz) made by fullsitebackup.sh.
# Website files should be in a tar file named filecontent.tar, and database
# content should be in a sqldump sql file named dbcontent.sql. This script
# expects the sql to drop the table before readdding the data. In other words,
# it does not do any database preparation.

# ----------------------
# 05-Jul-2007 - Quick adaptation for MediaWiki (currently testing)
# ----------------------
# March 2007 Updates - Version for Drupal
# - Updated script to resolve minor path bug
# - Added mysql password variable (caution - this script file is now a security risk - protect it)
# - Generates temp log file
# - Updated backup and restore scripts have been tested on Ubunutu Edgy server w/Drupal 5.1
