Backup internal HD + External HD

[Grant Simmie]

I have a Mac Book Pro laptop (intel).

I will be keeping photograhs on the laptop internal and external (lacie, USB). I'll call it my "external data HD" for ease of reference.

I will be buying a new Lacie Firewire 800 External HD. I'll call it my "external backup HD" for ease of reference.

I want to:

- maintain a backup of the entire "internal HD" (Bootable)
- maintain a backup of the entire "external data HD"

With super duper can I set things up so that:

- the "internal HD" will be backed up automatically whenever I plug my "external backup HD" into the laptop".
- the "external data HD" will be backed up automatically whenever I plug the "external data HD" into the laptop (external backup HD already plugged in).

In practical terms I normally work from the pics that are stored on my internal but from time to time work on the pics on my "external data HD" so I only need to use it from time to time. I want to automate so I don't make and old guy mistake and backup the wrong hardrive.



Any sugge
