Do I realy need to backup my iPAD ?

[peled]

In my case I need to sync only the applications.
All the rest I just copy, to the iPAD. I already have back up on my PC and CD's for books, music,photos,Videos etc'

My backup on the iPAD is half a Gig ( Can't even select the proper location for the backup). I assume that most of it are the applications.
Now suppose something would happen to my iPAD.
All I am losing is my mail account, and some other definitions.
All my applications, can be synced back to the iPAD any way.

For some good reason, Apple treat the users as dumb, so when you select backup on the iTunes, there are no options.
I would like to backup only the iPAD definitions. No need for any application or data. Is there a way to do it ?
