(New to Ubuntu)

I just installed a fresh copy of 12.04 on my desktop plus some aps i had installed . I had wanted to know if it was possible to create like a default restore point as to how my pc is setup now? (well at least i wasn't able to find the option) Someone recommended that i can use aptoncd and burn my aps and settings on it and in-case anything ever happens i don't have to install everything again from scratch. I wanted to know if there was another option or if that best way to go about saving everything
