If running from shell, put this above the <?php "#! /usr/bin/php -q" without the quotes!!!
This script is dedicated to "Salk". You know who you are :)
This script runs a backup of your database that you define below. It then gzips the .sql file
and emails it to you or ftp's the file to a location of your choice.
It is highly recommended that you leave gzip on to reduce the file size.
You must chown the directory this script resides in to the same user or group your webserver runs
in, or CHMOD it to writable. I do not recommend chmod 777 but it's a quick solution. If you can setup
a cron, you can probably chown your directory!
IMPORTANT!!! I recommend that you run this outside of your
web directory, unless you manually want to run this script. If you do upload it inside your web
directory source Tree($settings), I would at least apply Apache access control on that directory. You don't
want people downloading your raw databases!
This script is meant to be setup on a crontab and run on a weekly basis
You will have to contact your system administrator to setup a cron tab for this script
Here's an example crontab:
0 0-23 * * * php /path/to/thisdirectory/dbsender.php > /dev/null
