First time use: Possible to back up without erasing Maxtor files?

[macbeginner]

Hello,

I'm new to SuperDuper. I have an iMac and a Maxtor 4 external backup drive.
I wanted to use SuperDuper for the first time, and back up everything from my iMac to the Maxtor.
But I did not do it, because I noticed that this process would have erased everything on my Maxtor. ... I want to the keep files on my Maxtor.
Can I use SuperDuper and back up everything on my iMac by backing it up to a folder on my Maxtor, and not erasing what's already there.

Thanks very much ... MacBeginner
