backup: automount and launch an script

[Alberto Fuentes <alberto.fuentes@qindel.com>]

Im planning to have an external usb disk that i can plug to all my 
computers, and without interaction, sync all data i want with the disks. 
Also, umount at the end and send me and email with the details of the 
backup attempt.

The only part im not sure is how to automount the disk and launch the script

also, if you know of some tool that is already able to perform all these 
tasks, it would save me some troble :)

thanks!
