I use Simple Backup to backup my home directory. I save the backup file to /media/disk/ ie. an external harddrive. I would like it to be done automatically. Now, as I don't have the external harddrive running all the time, I have to run Simple Backup manually, each time I switch the external drive on. If I set up Simple Backup to backup automatically and the external drive is off, a directory "/media/disk/" is created on my root partition.

Is there a way to get Simple Backup to automatically run when the harddrive is plugged in, or to prevent Simple Backup running when the drive isn't plugged in?

Appreciate any help or reference to other programs!
