How to download and store ubuntu installation packages for future use?

[Ion.Lifesong]

Hi. I'd like to find out if it's possible to download and store (not install) official Ubuntu installation files, and then choose to install them whenever. I don't always have internet available and having to be connected everytime I want to install a program really sucks. What happens if I had to format or something and I just wanna install all my programs again but no internet connection? I'm new to ubuntu, please has an one got any ideas?
Is there also away I can back up my Ubuntu and when I restore, I get all my downlaoded and installed programs back, without having to re-install?

Thanks

Hi,
Is it possible to back up my ubuntu so that when I have to restore later, I get back all the programs I had installed without having to download and install them again?

Thanks

try aptoncd. it is in the repositories. you can burn all of the packages you want onto a cd for later use.
