Totally new and I know nothing and need help

[bscherokman]

I have an iMac, time machine, superduper and a brand new Lacie external drive 500 GB. I would like to use superduper for cloaning purposes and time machine for incremental backups. I read the SD manuel and also looked at every post on the SD discussions. Can someone please take me step by step through what I should do. I imagine I need to partition the Lacie for SD and TM but I do not know how to do that and I do not know how many GB to put into each partition. I am a neurologist and I missed this day in medical school. Please help with step-by-step directions. I thank you and my patients thank you.
