BigV,
There are primarily two kinds of "backups" you can do. One involves cloning, or making an exact copy of your HDD (aka ghost image), and the other involves just backing up your personal data (favorites, my documents, desktop items, PST folders, and any other data files you may have hidden somewhere on your HDD). Almost all of computer manufactures provide you with what’s called a Recovery CD/DVD, which is really just a ghost image of your HDD. The recovery disk will reinstall your operating system, all your device drivers, and any crappy software that usually comes with your computer. Because they give you this recovery disk, the best type of backup to do is usually the one, where you transfer over just your files and not make an exact copy of your HDD. The reason for this is that you don’t want to transfer over all the junk too. Over time, your HDD fills up with several unnecessary temporary files, cookies, spyware, viruses, and other useless stuff. Most people notice that over time there HDD’s will begin running slower than when they first purchased there computers, this is usually why. Now to answer your questions about how you can backup using the methods I listed before, here’s how:

DVD meets the goal in two ways:
1. you can either clone the HDD and make your own recovery disk using a program like Norton Ghost, or
2. You can just burn your personal data onto the DVD and make a data disk.

Online backups are primarily used to save normal data files (music, video, pictures, and office files) but you can also backup a .GHO file, which is an image of your entire HDD.

Raid, or Raid 5 to be more specific requires multiple HDD’s to hold a little piece of data about another drive, then if that drive goes down, they can fill in the blanks. Here’s a diagram:

SSD or Solid State Disk is no different from a regular HDD except that it has NO moving parts. This means the failure rate is VERY low. In essence a SSD is like a giant USB flash/thumb drive. Takes a lickin and keeps on tickin.
If you have any other questions, please feel free to ask.
