This appears to be a very good solution, I like the fact that it operates at O/S level and is independent of the Joomla installation, but by using e-mail your site's contents could be exposed, this would be a problem if your database contained sensitive data (user details etc)

How do you install this? It won't install as a mambot.

This solution was a good start to save my site

I changed the image backup to save al files modified the last day, by using the statment below

# Backup all changed files in last day
find $WWWDIR -type f -mtime -1 | xargs tar -zcf $BACKUPFILE

The Var $WWWDIR is my Joomla Home dir

A great solution for generating backups of your current content changes then moving the archives off the server. I've had to change servers recently and Automated Cron Backup was a life saver.

I use this for my sites and it is great! I have it set to 3 days a week and I copied the code within the file to do 3 of my sites at once.

Only down side is if your zip file is over a certain size, some of the free email systems will not accept it. The image folder is too large for one of my sites, but all the others work great!
