Hi Charles.

You might find this php script I wrote handy:

I use a seperate 500GB drive just for storing backups of 
various things I don't want to loose. Then at certain 
intervals (ie when I think needed), I burn the backups to CD 
or DVD - just to be extra safe!

Most of my backup scripts are run by cron jobs overnight.

Kind Regards,

Keith Roberts
