Good article.

Most of us, like you, can use a CD to back up.

However, I use one of the methods mentioned in the article - using ¨someone elses¨ HD for a back up device. In my case, it's my HD in another computer on the network. I have a very large HD as a slave and save anything I create or modify there. It works great. For an example, I do periodic maintenance on my machines but have, at one time or another, had to do a complete reformat and reload because of a particularly nasty set of viruses. It's easy with my method (that computer doesn´t have any internet software). The stuff I really need is right there on my backup hard drive.

The article mentions fiber channel but that's expensive and only really needed in a corporate environment. A less-expensive, new alternative is iSCSI, which is being marketed right now. And I saw a 250 GB drive in Sams´s the other day for less than $100.

I use both hard drives and dvd's.

Because HD's are a mechanical device I use them for daily backups but still do regular DVD burns.

Nero 6 does great multi DVD backup sets
