Time Machine

Listers I am having a hard time understanding a particular problem  
with Time Machine and Super Duper. For Time Machine it appears that it  
is making duplicate copies of the same data. For example when I  
plugged it in for the second time in life it said it is backing up  
19GB of 19GB. I have a total of 155GB allocated for Time Machine and I  
already have 40 or so GB gone. It's on the same drive as the first  
backup that was done for the first time on yesterday. I only have 19GB  
on my laptop hard drive so I can't understand why it made a duplicate.  
Also it does not automatically start backing up when I plug in the  
drive. What setting do I need to change in order for this to work.
I installed Super Duper and used it for the first time on yesterday  
and set it to backup the drive on another partition and had it to  
reboot from that drive once it finished. I ejected the drive and moved  
the computer to the other room and stuff started to act funny. I had  
deleted some items and other things like podcast. When I plugged it  
back in and turned the computer on is when everything went back to  
normal. The only thing is the data that I deleted was back on my  
machine, so I don't know where I messed up. I guess in short I don't  
know how to backup using software and need some pointers. I am use to  
just copying something to a hard drive. Thanks
