Workflow for Backups- newbie to SuperDuper

[BobT]

Her are my questions, and background information.

My questions: Is this a proper backup plan? If not, what do you suggest?

I now have a Sandbox BU, and, have restarted from the Sandbox partition.

I have a basic backup of my Macintosh HD to my SuperDuper partition, along with one Smart update of this backup.

I have setup another Smart backup of my Macintosh HD to my SuperDuper partition for early in the AM daily.

I plan to continue booting from the Sandbox until I need to re-install any new stuff to the Macintosh HD, and, will use the suggested Desktop folders for this between both "boots".

I have a 500 GB Macintosh HD, and,my external drive is a 300 GB Maxtor OneTouch II using firewire connections. It has a 40 GB partition for the Sandbox, and the rest is for the SuperDuper backups.
