Basic Server Backup Script Using tar & bash

This Script will backup the following directories as tar files with the date and location in the title of the resulting tar files:

/etc (location of most of the systems configuration files)
/home (location of users home directories/files)
/var/log (location of most of the systems logs files)
/var/www (location of webserver files and content)
/var/lib/mysql (location of raw MySQL databases, all databases are first dumped to a .sql file before the directory is tarred)

The tar files will be stored in:
/root/serverbackup/$DATE/ These files can then be moved or another separate storage media to complete the backup.

The tar files will be named like this example:
01-Oct-2009-Thu-04:46:42-AM-PDT-host.example.org-etc.tar.gz

Copy The Script above into the /root directory.
chmod +x serverbackup.sh
cd /etc/cron.daily; vi 00serverbackup (hit 'i' to insert text)
Add this line:
bash /root/serverbackup.sh > /dev/null 2>&1
Hit 'esc' :wq to exit vi
chmod +x 00serverbackup

Copy The Script to /root
chmod +x serverbackup.sh
./serverbackup.sh

The script will output to the screen so you'll be able to see what's being done. Once it's finished check the /root/serverbackup directory for the tar files.
IMPORTANT: You'll also need a MySQL DBA with full DBA privileges. The default DBA in the script is: backupdba password: dbapass. Change these to suit your own needs.
