Hi,
1.- Some notes on CRON :
http://wiki.osclass.org/Cron Please, full read, Explanation + how to configure + some cases
2.- Edit index.php of the plugin
// MODIFY THIS PATH TO THE ONE YOU WANT THE BACKUPS TO BE GENERATED
// DO NOT USE A PUBLIC PATH
$path = osc_base_path();
Change $path to whatever you want, consider putting it out of public view (if not, anyone will be able to download your database!)
I also recommend this one script (not osclass related!) :
http://www.debianhelp.co.uk/mysqlscript.htm I'm sure there're more like this, but I worked with this one. This has more options (multiple databases, keeps only the last 7 backups to save space, SEND THE BACKUP via EMAIL -only for small databases-,...)
The problem is that the order of the backup is not the correct one for OSClass, so improt will fail and you will need to modify it by hand.
I wish I had the time to make the plugin as big and useful as this other script. With sometime, I think we could make it, at least, to be able to roate backups (save HD space) and send them via email or host in other place.
Thanks!
